Apex1 exasut Rasp delete

[Croan]

I have a ka24de with 2.5 into a high flow cat, resonator, into the NA N1. and it sounds like hell. how do i get that deep , raspless tone. ? also wat would i sound like if i just cut off the N1 and piped it out?

thanks! all coments appreciated

Make sure everything's tighten down, buy new exhuast hangers, and make sure there are no leaks. Lots of people have the N1 including me and it should give you a deep throaty tone.

[Croan]

there are def no leaks. sounds ok when ideling around, but when i get on it its really raspy. like a civic rasp

[clark]

i have an N1 style, nice and deep. but it sounded worse/louder/shitty when i had the silencer in.


do you have the silencer in?

[Croan]

no silencer. do u think its the resonator? or i was thinking maybe its the can. are u guys running the 2.5 or 3 on the can itself?

I have the same setup but 3inch piping. Shit sounds mean and deep. I do have a little rasp while clutching in high revvs but that's cuz the bottom bend is fucked from having my shit slammed on coilovers before. Bout to cop me another, damn I love that setup. <3

all 3in or just a 3in n1

[Croan]

im stumped. i dont wana sound like a rice car : (

[AnarchX]

All 3inch piping. The tip is 3.5 and the canister is like 4.5.

[Croan]

i want that sound. no one has any ideas ??

[xsparc]

could be the resonator, mine is really raspy till it get warmed up, then its fine.

[Croan]

mine is kinda that way too. but it doesnt goo ALL away.

[los_inc]

get a new resonator welded in one of those vibrant ones should make it less raspy -los

[onehalfasia]

it might be your high flow cat, or resonator, more likely the cat, but its probably not the Apexi's fault, i'd recommend having the muffler shop add another 2.5in ID resonator, atleast a 15" It'll be deeper, and the rasp should decrease.

[Oo_Skyline_oO]

its the cat. I had the same problem, take the cat out and it will sound good.

[Croan]

why would it be the cat?? and putting another resonator will make it more quite wont it?

Louder =/= No Rasp

Louder = More Rasp

You need to either put your stock cat back in and/or add another resonator to make the exhaust sound deeper.

[Teknolust72]

I assume this is all custom piping, right? It sounds like it could be the cat and/or resonator. If there are differing inner diameters on your exhaust, it will sound like crap.

For example, if your cat is 2.5" ID, then a short section of pipe that is 2.5" ID, then a resonator which might be 2.7" ID, then some piping that is 2.5" ID, out to your Apexi N1, it will result in weird backpressure which causes some raspiness.

Also, if the welds arent clean and/or your exhaust has a crap load of slip joints, then you'll have some raspiness.

[greddyguy]

get a buddyclub spec2, that'll give you a deep throaty tone

[Croan]

haha i love spec 2s . thank you teknolust !!!

Is this a custom with an N1 muffler or an N1 Cat back system?


But I generally agree that the KA needs a big resonator to sound nice.
