Sound Deadening

[LA Kings]

So ive been looking around for some sound deadening material to use in the rear hatch area and under my back seat to help eliminate the exhaust drone noise problem i have. I looked up Dynamat and Raammat because they were the only companies i was familiar with and the prices were just out-f***ing-rageous. recently a new company has popped up out of Texas called GT Sound Control and i saw that they were offering free 10sq ft. samples to anyone who was interested in their product (they are still doing it just call 1-855-GT-SOUND) so I called them up and had them send me some of their material.

Compared to before it is a night and day difference. My exhaust noise was cut down by 60-70%. I am 100% satisfied with their product and if you are in the market these are the people to call. +1 for a legit company with a legit product :rawk:

[LovetoSlide]

How's the weight of these compared to dynomat or those other products?

[LA Kings]

GT Mat:
10 sq ft of 80mil product weighs 3.14 lbs.
10 sq ft of 50mil product weighs 2.80 lbs.


Dynamat:
10 sq ft is roughly 4.2lbs

[zooopreme]

EDIT: Nvm, found their site. Going to give them a try!

PS. with your set up, how do you expect to get to your fuel pump?

Razor blade. Fuel pump is new so I don't see me needing to access it any time soon

[MAHALOHAWAII]

just called them and about to ship me a sample to hawaii! LEGIT!

[Turtle]

how much ft^2 did you use to cover that much?

[240SilviaX]

LA Kings,, So no purchase necessary? how much did you use in your car? 10sq ft or more.?

[hOngsterr]

their material looks slightly thinner compared to dynamat, im running dynamat in my car atm.

[Okinawandrifter87]

I wonder how this compares to second skin?

[LA Kings]

how much ft^2 did you use to cover that much?

i used 20sq ft

[LA Kings]

LA Kings,, So no purchase necessary? how much did you use in your car? 10sq ft or more.?

no purchase necessary for the free 10sq ft sample. i used 20sq ft

[240SilviaX]

Just ordered 20sq/ft today, great customer service, super easy to make an order.

[jamg]

going to look into this.. in for a quiet car!

edit: just ordered. 23.74 for 20sqft.

OP what exhaust are you running? I was thinking about running with an STi muffler, but if the sound deadening works that well, I won't need too.

exactly how much of a difference does it make?

im running a Greddy manifold > SR20 downpipe> Apexi dual N1. difference is night and day. the apexi exhaust has a really really deep throaty tone that loved to vibrate everything. now that i installed the deadener i noticed a 50% decrease in vibration and a 60-70% decrease in overall noise

do you think there's a need for me to get an STi muffler then?

have you seen the inside? it really makes a 3" exhaust quiet.

I'm not exactly sure what's going to happen to all that when i shoot flames haha

not even gonna lie, i know nothing about the internals of mufflers and how they work. i mean your cheapest route would be to try the deadener anyways so id start with that. if you dont like it at least its only like $20-$30

[240SilviaX]

This stuff is awesome, ordered another 25sq/ft of it, and prob ordering some more. I want nothing rattling cuz of the sound system I have.. even stuck some on the plastic interior panels. They ship really fast. Highly recommended ppl

[Kingtal0n]

Let me see if I understand:

1. The car is perfectly quiet to begin with but you decide to make it noisy by adding a noisy exhaust.

2. the noisy exhaust annoys you so you add weight to your vehicle to stop the sound.


I have a problem adding weight to my daily. Why not just remove the noisy exhaust instead?

its crazy. I can see the next step:

3. the car is too quiet again so I install an even noisier exhaust
4. the car is too noisy again so lets add more sound absorbing material!

Heres a better idea;
Install an electric cutout on the OEM exhaust. Noisy when you want, not when you dont. /thread

[jamg]

Exhaust systems benefit turbo motors.

The addition of 10-15lbs is not going make a significant difference.

How about you lose 20lbs of fat is you are so worried?

:rofl: :rofl: :rofl:

I don't understand people with their junk ass 240's on this forum thinking that adding 20 pounds is going to significantly slow down their "rockets".

You shave weight by adding better aero, lighter rims, lighter/better engine parts. But for people who actually want to restore their 240 to feel more modern; they add luxuries like sound deadening. I don't know about you but even my "meticulously owned", stock ass 240 creeks every now and then. It's a fucking 20 year old car!!! :picardfp:

The S15 silvia sr20det is capable of putting down 280rwhp through the oem exhaust system.

Now tell me, guys, where is your 300+rwhp that requires an aftermarket exhaust? Does anybody in this thread actually own a turbo engine producing over 300 horsepower that necessitates the noisy exhaust system?

[Boost_Fiend]

I wonder how this compares to second skin?

I recently did my car from the firewall back with second skin and its awesome. I don't have any experience with other products but my results with second skin are great and my exhaust is LOUD!

[jamg]

A less restrictive exhaust benefits turbo motors... So is this now about loud cars, or saving weight?

[Promise Land]

I used DEI Boom Mat on the interior of my S14. It cut down on exhaust drone but the Energy Suspension bushings also add interior noise. I will eventually replace the exhaust since the previous owner added a 3" race exhaust which is stupidly noisy.

[240SilviaX]

OMG extra 20lbs!!! who cares ,, its their own car , do what u want , there always some one trying to trash ur idea, lame

[240SilviaX]

My amps, subs, box add 80lbs not worried about the sound deadening weight lol. And who would want a stock exhaust on their modded 240? Not me

[MrSanchez925]

I dunno what that guy is talking about... s13's are fucking rattle boxes. Hell most cars that aren't luxury cars from the 90s end up being rattle boxes.

My car has rattles and tons of road noise and I have full interior!

Time for some sound deadening =) i love quiet rides.

Lmao I have a 300 HP capable motor; though I run a moderate, daily boost of 6 psi. My cat is gutted, but I'm running a lowkey muffler on my 3 inch straight pipe. It sounds quieter than a KA that's for sure under low RPM's but some people daily their 240's and I'm sure they're trying to make their 240 more luxurious to either themselves or the people they might drive.

[hamizle]

I want to see in a actual comparison test against dynamat. I've heard nothing but good things aside there price but it might be worth the extra bucks if it actually works better.

[rwtf]

I just got me a free sample!!! wewt.

Work's great, did it to my 350Z when I installed the sound system. All that "tinny"-ness was gone, sounded like a German car after that.. Door thunk and all.

350z's aren't that old so they don't have as much road noise as an S-chassis either way
I ordered a 10ft sample and I'm excited.

FREE 10ftsq > $8 roll

[zerodameaon]

I have been thinking more and more about putting in sound mat in my car but I think the only way I could benefit is if I just stuck it to my ears every time. Damn convertibles.

OP thanks for the heads up on this deal.

+1 There must be a reason why dynamat has been the leading the industry is sound deadening all these years. The phrase often imitated never duplicated comes to mind. But hey, prove me wrong and ill be a believer.

[Sauce98]

Just what I need, this is awesome. I'm calling tomorrow. Thanks OP

[mrizsuki]

lol, any type of sound deadening will REDUCE tons of noise in any car, especially our s-chassis. for the weight part, anyone who carries a tool box will already add easy 20LBS-40LBS to their car + golf clubs. so weight is not an issue. +1 for peaceful luxury silence

[Kevin_S14]

do you know if they still offer the free 10sq ft? im kinda interested in this

[Corbic]

Oh noes guess that means it won't work in old cars. What the fuck ever bro. I can only imagine what they charge when the free sample is up.

[EDacIouSX]

Oh noes guess that means it won't work in old cars. What the fuck ever bro. I can only imagine what they charge when the free sample is up.

dang dude, it's just sound deadening lol.


Why pay $8 bucks now when you can get some stuff for free? Why not take advantage of it?

[GTMat]

We always welcome comparison of our GTMAT product to premium products like Dynamat Xtreme and Damplifier Pro. While we market our product as a discount product with published differences, we do understand there will be feature by feature direct comparisons. As you know the higher end products use Butyl and we have and asphalt based product. Butyl has a different smell and has different heat-related properties than asphalt based mats. Lets be perfectly clear: GTMAT is not claiming to be better than Damplifier or Dynamat Extreme. If you can afford to do your job with Damplifier or Dynamat Extreme, you should as its features are the best you can hope for in a sheet product. But if you need a discount alternative, GTMAT is worth a look. For the price, GTMAT gets the basic job done, almost as well as the high-dollar premium products, and much better than the 'garbage' at the hardware store.

That being said, our free sample is 100% completely free, we pick up the shipping charge as well. So why not give us a test drive?

Now tell me, guys, where is your 300+rwhp that requires an aftermarket exhaust? Does anybody in this thread actually own a turbo engine producing over 300 horsepower that necessitates the noisy exhaust system?

To answer your second question: Yes I own a turbo engine (sr20det) producing over 300 horsepower that necessitates a noisy exhaust system.

And to answer your first question: My 300+rwhp which performs extremely will with my 3" aftermarket exhaust is in the driveway.

Any other questions?

[kojiki88]

Just called in for the free sample, I should get it in 3 to 5 business days. I have never tried the other products but I will give a review on GTMAT once I put it in my S13. I'm not worried on the weight added with this since I am pushing 300 RWHP (Oh, I also have a 3" turbo back exhaust. Even though its not unbearable, anything that helps quite down the cabin its a win win situation.) Thanks GTMAT for the Free sample!!

[ghoti]

Oh noes guess that means it won't work in old cars. What the fuck ever bro. I can only imagine what they charge when the free sample is up.

Read first! I said they don't have as much road noise. 240's have much more than speaker rattling
dang dude, it's just sound deadening lol.

^ +1 You got it. Why not take advantage of it while it last free is always good

[240SilviaX]

GTMAT is the shit, They ship fast, i covered everything from the hatch to the rear of the front seats

[DreamN]

I've always wondered how products like these are suppose to be used. I've seen install photos of people covering damn near the whole car in the stuff and some who do selective strips? Which is it? If the latter, then how do you go about selecting the actual areas to be covered in the stuff?

[nismostormtrooper]

GTmat is pretty legit, used it to get rid of the rattle from the rear deck. Worked perfect!

[Mikester]

:blah:

That being said, our free sample is 100% completely free, we pick up the shipping charge as well. So why not give us a test drive?

I'll tell you why, sir/ma'am- Because the good stuff doesn't have asphalt in it for a reason...

Totally LOL'd when I read your Rico Suave way of saying your product "has different heat-related properties..." Translation: It sucks in the heat! You can't use asphalt-based products near anywhere that has the potential to get hot (firewalls, over exhaust areas, CA, AZ, TX or anywehere else that has hot summers)... Unless you like a mess in the driver's compartment and the inside of it smelling like a freshly paved road... The reason? Physics- Asphalt becomes pliable and melts when even mildly heated- much like how the road gets squishy when it gets hot.

The good stuff on the other hand, not only deadens sound and reduces rattles wonderfully; it also "can withstand temperatures of -30 to 400F" (Source: Summit Racing® Ultra Heat and Sound-Deadening Mats SUM-879006 - SummitRacing.com (http://www.summitracing.com/parts/sum-879006/overview/) ... which is what I used). Not all of it is as expensive as Dynamat; but if you want quality, there is still a price to be paid for it.

In otherwords, if you are an S-chassis owner who has already polluted your car with knockoff "discount mods" because you are on a budget; this "discount alternative" may suit you nicely. However, with your best interests in mind; I strongly urge you to reconsider this one- There are just some things you shouldn't skimp on.

BTW Props to the dude who used the $8 Peel & Seal. Not my first choice, but I bet it will succeed where GTMat will not.

[240SilviaX]

LoL @ Mikester ,, my car is black and has been sitting in the direct sun every day and my car gets hot like 140* inside since we have been getting these recent heat waves in CA. GTmat is rated up to -100*F to 300*F and had not melted away untill 375F* in tests.. so lets average 50*F from your Summit racing stuff that you paid $100 more than I did for the same amount of material... Not once has my car started to smell like asphalt or has it started to melt away. But its nice to hear your assumptions, the Peel and seal type from the hardware store will melt away way b4 the GTmat will they have tested it and made a video of it. And discount budget haha, Why pay more for sound deaden-er when I can spend that money on my Powered By Max parts .. just looks like another person likes to talk shit and has no idea what he is talking about.

[240SilviaX]

And no where in the summit page it says what its made of, so all n all you have no idea if its a asphalt or not. just sayin..

[dizzariot]

Awww you guys :hey:

If you have 'real' wheels: use Dynamat.

If you have fake wheels: use GTMat.

Maybe now you can stop bumping your peepees together now.

Actually, I did extensive research knowing that whatever I put in was going to be a permanent fixture... This is what Summit carries under their house brand: Frequently Asked Question About Hushmat (http://www.hushmat.com/index.php?customernumber=246637587545706&pr=FAQ&faq_step=showfaqs&selink=1)

^^ Clue in to the part where it says "Why doesn't HushMat offer an asphalt or PVC damper like the “other” guys? (http://www.hushmat.com/index.php?customernumber=246637587545706&pr=FAQ&faq_step=showfaqs&selink=1#q60)"

LMFAO hahaha hurt feelings report how cute you posted than instead of responding on my facts that makes your "translation" bullshit. It does everything its designed to do well. Far from hurt feelings. I had a great day got alot of stuff done to the car, thanks for letting me know you care ;).. who cares lol, it does its job doesn't melt or smell so who gives a fuck. and I saved $100

I have been a high-end car audio dealer/installer for 20 years now, have personally done installs on over 25,000 vehicles and I'm a Second Skin dealer to-boot... and that post I just quoted is the most honest reply I have ever heard from a product rep/manufacturer. Most reps just say their product is the best you can buy and talk it up like they are re-inventing the wheel... I get sick of it.

Kudos to you man... I may just have to try your product out as a cheaper price point product.

[Corbic]

Well I just placed an order. Well see how this does on the my S13 when it gets here.

I currently have all poly bushings, solid subframe mounts, welded diff, SR, 3" straight exhaust to a Mag. Muffler a FMIC with no BOV and mechanical fan.

Unlike my Tacoma, there is no confusion if the engine is running!

Another product out there is Fatmat, I may try some of there's as well, although ion not sure how to do a comparison without striping out and changing over the products.

You are more than welcome to state your opinions but I would advise people to take your information with a grain of salt as you have not even attempted to test our product yourself. GTMat is located in Texas and the majority of installations have been in Texas where, as you know, summers can hit up to 115 degrees. We have several employee vehicles that were covered in GTMat during the summer and have not had any type of melting issues. We have also shipped samples to California and Arizona in the summer and have not had any reports of melting from these customers. As far as an asphalt smell, our product has been engineered to have very little to no smell. Most of the free sample users who reported a smell, noted that it was hardly noticeable and dissipated after a few hours of installation.

Take a look at our test video and feel free to call me when you are ready to give us an honest review.
And by the way, it's ma'am and I will be installing GTMat on my 370Z doors this week. I'd be happy to take a video for you showing the temperature here and what not if you wish. ;)

I'm not one to make excuses; so with the utmost of respect to you, I apologize for being so brash. The guy up there was correct- your synopsis of your product was very honest; and I find it admirable that you even recommend higher-end, butyl-based deadeners over your own to those with fewer budgetary constraints.

Also- thank you for offering me sample in spite of how crappy I came off. Right now, I have no need. However, in the event I ever decide to build a second keeper, I may consider taking you up on it.

[240SilviaX]

LOL ,, Ive done my research too ,, coming from a first hand experience, having the product in my car why would I bullshit?? I know the stuff I put in my car is good like GTmat so there's no argument. Is good stuff period. Thanks for your honesty

i swear 240 owners are never satisfied.

stuff is over priced with a drift tax, people complain. stuff is free, people complain.

Liqui-Damp can be used in any place where you would consider matting. We recommend it to be layered over GTMat for the best results. People find the liquid product to be easier to work with surfaces with nook, crannies and hard to reach angles where mat will not work.

OP did u remove the stock sound deadening before install?

Agreed, i also received my sample roll and it works great. Definitely much quieter cabin. I will definitely be looking into getting enough for the rest of the car. Thanks again.

Dangit...looks like I missed the free sample. I'll keep you guys in mind when it comes time to redo the interior this winter.

yes i had previously removed it when i installed the new carpet kit. I just had to peel the carpet from the floor board, lay down the deadener, and re-apply the 3M carpet adhesive and I was done.

I have been a high-end car audio dealer/installer for 20 years now, have personally done installs on over 25,000 vehicles and I'm a Second Skin dealer to-boot... and that post I just quoted is the most honest reply I have ever heard from a product rep/manufacturer. Most reps just say their product is the best you can buy and talk it up like they are re-inventing the wheel... I get sick of it.

Kudos to you man... I may just have to try your product out as a cheaper price point product.

Hey guys, wanted to update you on this. We are no longer offering the free 10sq ft samples but still providing a smaller size sample of all three mats.

We just launched GTMat Onyx, our butyl based deadening mat. Pictures and prices can be seen here:

GTMat Onyx - eBay (http://stores.ebay.com/GT-Sound-Control/_i.html?_nkw=butyl&submit=Search&_sid=746164080)


Of course, I am here to answer any questions you may have!

[GTMat]

I'm not one to make excuses; so with the utmost of respect to you, I apologize for being so brash. The guy up there was correct- your synopsis of your product was very honest; and I find it admirable that you even recommend higher-end, butyl-based deadeners over your own to those with fewer budgetary constraints.

Also- thank you for offering me sample in spite of how crappy I came off. Right now, I have no need. However, in the event I ever decide to build a second keeper, I may consider taking you up on it.

Hey Mike,
Now that we offer our own butyl based mat, maybe you can give us a shot? :)

I'd like to offer you a small testing sample. I'm interested in hearing some feedback from a professional installer. :)

[e5s4y]

if i used about 80 square feet of the gtmat, how much of the liquidamp would you recommend to cover that?

Got my GTmat in the mail yesterday and spent a couple hours this morning laying down an initial layer. The product is awesome is awesome, the quality is really great. I ordered 25sq/ft and I have a lot left to finish the center once I grind out some rust.

Going to be installing my 10ft pretty soon in my corolla and will update this thread, depending how it comes out I might be buying some more to finish off the car cause I know 10ft won't be enough

[e5s4y]

i need to put up some of the pics i took, but i installed about 80 sq. ft. of the gt mat (removed all the oem crap first) and it made a pretty noticeable difference. still need to install it behind the door panels tho.

[GTMat]

Thought I'd share some pictures of the GTM Supercar that we sponsored with Liqui-Damp.

GTMat how much weight did it add? I will be doing the same thing to my SL-C when I get back from overseas. Did it bring the noise down to a "stockish" level?

[future]

So after doing the 10ft I was only half way done with the trunk. Ordered another 10 feet to do the other half. The before and after differences is disappointing. I might try their top of the line stuff but sceptical. Cause I noticed no difference before and after. I know Toby sells some great stuff but his is more then double the price. So still debating and don't have the funds anyways to blow on it. But as for GT bottom of the line stuff. Save your money.

I don't believe he used the entire gallon, so I'm unsure of how much weight was actually added on. A gallon comes in at 13lbs total though.

The car is still being built so I have no feedback on noise level just yet.

Sorry you feel that way. I've posted before that 10sq ft of the 50 mil will reduce cabin noise by 3db on average at idle. 10sq ft of the 80 mil bumps up to 5db on average.

If you're looking for full sound deadening, you will need to go the full route with closed cell foam and mass loaded vinyl.

If you'd like a sample pack of all 3 mats, let me know and I can drop it in the mail. It might give you a better idea of the premium product vs Pro and Ultra. :)

^^^^This....

As an old guy I want to point out, as Broadfield did awhile back, that it is EXTREMELY RARE for a manufacturer to support their product and customers with such vigor and focus upon customer satisfaction.

GtMat you sir deserve a kudos.

My car is nowhere near ready for interior work (stripped for paint), but when it is be expecting a phone call to discuss what will work best for my needs.

Deff hav great customer service! Don't want to feel like I'm only talking negative about you guys.

[Kingtal0n]

Here is something I was wondering. We all know a 240sx with zero modifications on the highway at 80mph is not exactly a solid ride.

Once you get some decent suspension components installed, the handling and highway feel improves and smooths. But the shake and rattle is still there, unless we attempt to do something about it.

My favorite part of driving a supra or camaro on the highway at 80MPH is the stability and the comfortable interior noise level. IF we attempt to "do something to our 240sx" In order to make it more like a "supra or camaro" on the highway, without adding 1000lbs of course, where does all this noise damping material need to go? The trunk seems like an obvious place. But what about the actual undercarriage? Or under the actual carpet? We are not seam welding the chassis or adding a tube frame- and adding 100lbs of sound deading material is not going to add the extra "1000lbs of car" feeling that a supra or camaro gives on the highway.

SO- heres me wondering what and where are the key point, places, aspects of this sound eliminating idea, that also reduces vibration, and gives us that extra "1000lbs feeling" without actually adding that much weight.

It sounds like you want the rattle vibration gone plus the quiet interior of a more modern car, correct? If so, you will need to go the full route of mat + closed cell foam + mass loaded vinyl. I always advise people to install the mat in the trunk/hatch area (especially over the rear wheel wells) and doors. The floor should not need any mat unless you are working with a completely stripped vehicle. I'm not sure about the weight of the CCF and MLV since we do not carry these products, yet. The weight of all the mats per square foot is listed below.

GTMat Pro 50mil - 4 ounces
GTMat Ultra 80mil - 7 ounces
GTMat Onyx 70mil - 9 ounces
GTMat 110mil - 9.5 ounces

A Couple questions, so installing this material under the carpet of the interior will not see a benefit? Also I would like see a sample or more detail on the "closed cell foam" since I could not locate it on your website.

If there is none or not enough factory installed lining on the floor, then yes, installation does help reduce the noise and resonance. I haven't looked at my floor but it is possible that companies are skimping on this so it might be something to look at. In most installs that I've seen, doing just the rear, wheel wells and doors was enough.

We do not have a closed cell foam or mass loaded vinyl product at this time, as stated in my previous post. It may be in the works in the future. :)

I just ordered a sample off your website. What is the sound deadening ability of the 70mil onyx vs the regular 110mil. I know the onyx is the better actual product due to what its made with but will it deaden sound as well? I live in south Florida and have a 98 240sx. Which would you recommend and how much of it to do the whole trunk and doors.

Thanks

Hey Tom, I sent you a PM. :) Give me a call to discuss!

[GANBATTE]

+1 There must be a reason why dynamat has been the leading the industry is sound deadening all these years. The phrase often imitated never duplicated comes to mind. But hey, prove me wrong and ill be a believer.

I think an alternative that is lighter, WAY cheaper, and has 70-80% of the noise
Reducing properties is the way to go. You get most the benefit adding anything at all from my exp.

I've also used "b-quiet" I think it was called. Worked great.

Quick question - would you recommend leaving the material exposed for a certain amount of time in order for the adhesive to dry or cure? for example leaving the car in the sun with the windows down to sort of "bake" it ? Was trying to see if I can also avoid smelling the adhesive for the next few months.

I have only had a handful of people who could still smell the mat two weeks after the installation, but it has never been longer than that. I usually ask people to leave the car in a garage with the windows down. I don't think keeping it in the sun will help get rid of the smell any quicker than leaving it in the shade. For my doors, I left the windows down and rode around with them down for about 3 days. I used the Ultra 80mil, 6sq ft worth on each door.

I have a s13 hatch, I installed the sample material in my door panels and the trunk area, did have a little bit of a odor that was not strong or anything like that, it only lasted for a week or so and it was not irritating, pungent, or smelled like tar or anything like that. It was fine.

I forgot to mention, we now have a pure butyl premium product called GTMat Onyx if you are worried about any smells. Higher heat resistance, no odor, 70mil thickness. Let me know if you want a quote!
