A "deep" exhaust sound using only a na KA24E

[tacobellman_2007]

Hey guys, what are some pretty awesome sounding exhaust setups you guys have seen and heard in person coming from just a stock KA24E? I'm trying to get an idea of what to get for my KA24E.

And no, please do not stray away from the topic and tell me "just do an engine swap" or "don't even waste your time." I am already planning to do an engine swap on my car. The exhaust I plan to get is just for me to use until I save enough money to do the swap. To be more specific, I'm looking for a nice, deep sound. A bit louder than stock, but not obnoxious loud. Something like this (skip to 0:42):

Lexus IS300 exhaust - deep tone/sound - YouTube (http://www.youtube.com/watch?v=y2pPMEKsziQ)

Yes, not a 240, I know. What's the CLOSEST I could get to that sound purchasing only exhaust components for a KA24E? It's not going to be exactly the same, I know, because it's a totally different engine and setup, etc. But with the ability to only change the exhaust system (not including manifolds/headers, either), what do you guys think is the closest I could get? Thank you.

P.S. I've also heard going with a 3" outlet will most likely cause you to lose a lot of low end, which I don't want. I'm looking more towards a 2.5" outlet. If my combo of "deep sound" and 2.5" outlet is not possible, let me know. Still learning about cars as I go :P

i was really impressed by my brm 2.5" catback system

[InsTanCeZ]

Generally, the larger the diameter, the deeper it will sound. So I would just go with a 3 inch or bigger if possible. The thing about losing low end is a myth. It's been dyno tested.

Just got to youtube and find one you like...

I have a stock ka24e with an hks hi powered exhaust and an isis test pipe in replace of the cat. It idles very quiet and has a low note to it.

3" exhaust on N/A engines will sort of make the tone deeper. But for the most part, it sounds like a fart can.

Go with a 2.5" system. It's all you'll ever need on a N/A application. You'll see about as much benefit if not more than a not-so restrictive 3" piping. Like someone said before me, a BRM exhaust system + a long resonator will give you a real nice tone, not some fart can noise.

I know this is a 18" resonator but the 22" that BRM offers will make the tone deeper.

For a KA, an exhaust alone will not yield you any benefits so if you're planning on boosting the single cam, then you may want to go with a 3", but a 2.5" could also be used if you're not planning on making a lot of power.

Get Top Fuel!

[Karstondh]

My apexi exhaust has a really deep sound. I believe its 3", you should check it out.

[crzsteveo]

get different headers, stock exhaust, test pipe, some sort of muffler and your good to go.

[Reece]

I have a 4 inch outlet on my NA KA. (inb4 ricey or gay or whatever). I didn't notice any sort of loss of low end power at all and it sounds fantastic IMO. Really deep and awesome.

[zeebrah]

when my ka was na i had an ebay exhaust manifold, test pipe and topfuel 3inch with dented to fuck resonator with various exhaust leaks thru the system. shit sounded AMAZING. at the track NO ONE believed it was a single cam. super deep to about 3.5k then above that (if on it) it sounded like the gates of hell were opening up.
but yea id say try to find a top fuel exhaust and header.

[simmode1]

Exhaust on a N/A KA? Waste of money. Just gonna attract attention to you going nowhere fast.

No boost? No care.

[stuckonfresh]

I would look for an exhaust that has more than one resonator (more than just just the one in the exhaust tip). Resonators help to keep the rasp down and achieve that deep-toned exhaust note.

[rbs14kouki]

I felt in love with my greddy ti-c !!! To bad i sold it

[jlopez7354]

I have an apexi n1 dual catback it's not too loud and I'm very annoyed by overly loud exhaust when I'm in the car it's only loud when you want to it to be.

This^^ with header and 2 1/4 piping my car sounded like a nest of angry bees! I ended up throwin a cherry bomb on there and it smoothed out All the raspiness and had a deep low tone. GL!

this makes my car like a bat out of hell. and not super loud. just rumbles like a dragon waking up from an afternoon nap. its all exhaust components also, so it fits the description of what you were looking for.

+1 on that....

note to OP

better disconnect your BPT valve after fucking with your exhaust on the SOHC

otherwise, welcome to stumble city

What will disconnecting the BPT Valve do?

[ixfxi]

add a header and/or exhaust to a KA24E, you'll see how quickly it starts to stumble at low rpms

only fix i ever found was to disconnect the BPT valve. it controls the EGR based on back pressure.

thats assuming i actually have knowledge of what i am talking about

[tacobellman_2007]

Thank you all to those who have responded with actual exhaust products/setups/exhaust ideas. Will definitely help another 240 brother out like me.

[forcedproductions]

what is a BPT valve?

[twinspool]

what is a BPT valve?

I believe that is the valve on the back of the intake manifold that has a hardline connected to the exhaust somewhere. It's a bitch to get to with the intake manifold on the motor, or motor in the car.

what is a BPT valve?

Bpt valve controls your egr valve. Aka egr control valve. That tube plumbs exhaust gasses through your egr valve and into your intake manifold to be burned again. Egr system=exhaust gas recirculating system.

Ricey and gay.

technically... Exhaust is an Inert gas. cant be burned again.

Pretty much, but it's a cheap and quick mod and everyone has been there at some point.

Personally, I really liked the sound of the BRM exhaust zooopreme posted.

[apex]

Best sounding I've had is blitz nur spec or get
A rocket don't pop up much but they are dope

i liked my isis blast pipes but then went with isis mbse type-e and likes that a lot too

have you ever even gone to a place called school before, or bothered to read a book?

listen, i dont consider myself to be a scholar, but i can tell you that this is one of the most idiotic statements i've ever read on this forum.

exhaust gas is exhaust gas, its composed of many things.. hence the reason when you go for a smog test, they test the percentage of gasses found in your exhaust stream

argon = inert gas
helium = inert gas
nitrogen = inert gas

there is a reason why cars are equipped with catalytic converters... and thats to burn the unburned gas in the exhaust stream

you stupid fucking idiot

This is true. Exhaust is mainly carbon monxide, which is highly flammable in the right circumstances

pretty sweet sounding.
idk why so many haters are in here lol.. kick rocks

[SilviaSR20DET]

if you can find them, gp sports exhausts are deep sounding.

[Lethal240]

I have Isis Single GT , its a full 3 inch catback and its really deep and rumbly.

I'm usually not the type to be an asshole on here. But u sir are a fucking moron. Did u google inert? It means it does not succumb to any molecular changes. Hence why u use argon (an inert or noble gas) when welding. Exhaust is a by product of burning a combustible gas. and the egr system, as well as the cat is to burn unburnt air fuel mixture... If exhaust was inert then we would have no pollution

What? No it's not. It's bolted to the plenum like right on top. Towards the back of it. If you kept the AIV on then you probably had those problems. My old KAE had a 4-2-1 header, Megan resonated test pipe, SRS 2.5 cat back, cold air, and was fine with bot valve. I felt a diff with erg tube hooked up (loss of power) but it should be fine.

Go with a 2.5" system. It's all you'll ever need on a N/A application. You'll see about as much benefit if not more than a not-so restrictive 3" piping.
I disagree with this and am getting sick of posting the dyno's that prove it...

I know this is a 18" resonator but the 22" that BRM offers will make the tone deeper.
I agree. The longer the resonator the better.
