3" exhaust on NA, what are you guys running?

[Killa From Manila]

Looking for a 3" exhaust system for my h22 build and was wondering what exhausts people are running out there.

Theres rcrew and skunk2 but i think they will be too loud even with the silencer so any1 using a custom system?

[Brendan_Man]

i run a 3 inch system on my H2B setup

[Killa From Manila]

is it custom or an off the shelf item? n is it loud as fcuk? lol

Skunk2 Megapower RR (76mm) with the silencer in is as loud as my S15 with an Apexi N1 exhaust with no silencer.

[YBOOST]

i got custom 3" for the k20. its fkin loud!

[Killa From Manila]

^ ^ is that just with a resonator and canon muffler?

[jesmine0]

i got skuck2 2.75" with silencer, resonator and cat and i would say, it is loud.

So i am now trying to save for the xforce twinloop on axles back and hope could lower the noise

[EG5]

Got 3 inch exhaust aswell here
3 inch collector header , 3 inch custom catback
Works good

high flow cat, 3" with vibrant resinator and vibrant muffler shouldn't be toooo loud nice and deep imo - youtube it, and cheap or substitute vibrant for borla for more $$$, stay away from n1 or cannon mufflers. Magnaflow's are a little louder.

SSR header with metal cat and straight thru muffler at the rear with 3" dumpy from westside mufflers, padstow.

[fatboyz39]

3' is ok. We ran S2000 cat with 2 resonators + straight thru muffler. Wasnt loud on cruise but once WOT, its over legal limit.

[Dr.k20z1]

im running 3" no resonators with varex cannon.

[Killa From Manila]

haha no wonder its damn loud


im running 3" no resonators with varex cannon.

hows it sound with the varex canon? is it bad to drive the car hard with the flap fully closed?

[Water Boy]

Dont mean to sound dumb but isnt 3" pipe rather big for a NA engine.

3" yells turbo at me :confused:

[Killa From Manila]

yes it does seem rather big and most "exhausts shops" wud tell u to stick a 2" on there, but 3" is proven on the dyno to give great gains on H and K series engines

[Limbo]

i've seen a few and they are loud.
Just need to run a larger resonator and good quality muffler, will still be loud but, that the sacrifice your gonna have to make

[SHU-ES1]

i run 2.25" inch with hiflow metal cat, magnaflow resonator, magnaflow rear muffler.. and to me its perfect!

my bro's runninga 3" from header collector back with high flow cat, hot dog resonator and supercat cannon muffler back on his toda built dc5r and it is fkn loud as fk! definately cop bait!!

[thebob]

[Limbo]

is an S2000 cat plug n play / bolt on to a DC2R with JDM header and cat back? is there any different in AP1/AP2 cat?
cheers

[xntrik]

I dont think there is such thing as a quiet 3"
Even if there is I highly doubt it after 3000rpm.

[paps02]

i wanted 3 got 2.5".. its fukn loud.

let me rephrase. I thought you meant westside sells ssr's. Don't get me wrong they do great shit. Ssr's are the real deal. And your k20a is the real deal.

[YBJLS4]

im running 2.5 from headers custom piping magnaflow high flow cat to x-force twin loop. had 3inch canon before and it was pretty loud changed over to the twin loop and now you can only hear it over 2500.

[xntrik]

Well H2B Setup, 3" is a must.
Dont expect it to be quiet. lol
