im loooking to get a 3 inch exhaust for my all motor set up because i have a 2 and a half apexi world sport 2 right now, with 2 and a half inch piping want to upgrade to 3 inch piping and exhaust for a better flow and some power increases...

what exhaust would you guys recomend? i want something that flows really good preferably a PAN then those canisters tho they're too loud lol

also something not too loud because this is my daily! lol

any help would be highly appreciated thank you in advance

Mr. EG

Kteller 3 inch piping to a vibrant 3inch (inlet/outlet) muffler.

i heard they're pretty loud, true?

Most non restrice exhausts are going to be loud. I'm running 3inch collector to 3 inch resonator then a short piece dumping before the tank

You have to ask yourself this question:
Are you willing to sacrafice power for quietness or put up with noise for power? I have done that and decided to stick with my WS2. At the track I open it up anyways so have a quiet comfy ride around town is worth the power loss to me. If I was a street racer I might think otherwise.

use 2 big resonators i don't think they will hurt performance that much and keeping sound in logical levels .

thanks guys! i might just keep my ws2 just go with 3 inch piping on it.

Ws2 only comes in two sizes: 60mm and 80mm. The 60mil version is 2.36 inches and the 80mil is 3.15 inches. You can get a 3 inch piping kit from kteller with two 22" magnaflow resonators welded in and the 80mm ws2 muffler.

Did you try searching?

More info on your setup.. What are you running that you would even 3 inch? Turbo B Series? lol.

I would think 2.5 would be good. I'm in the same situation though, Running the Apexi WS2 on my Integra, when vtec engages it's a lot quiter, all you hear type R cam's screaming.. but i can feel a difference in power, it is restrictive.. I thought about having the resonator removed, but the muffler is still chambered anyway..

Mr. EG

It has been proven that a 3 inch exhaust will out- perform smaller diameter piping (even on B16's, etc.).

While I'm with you on recommending a search, I'd like to know what your thoughts were on asking his setup....Tests have SHOWN that pretty much ALL B-Series will benefit from a 3" exhaust over a 2.5"...YES, even B16s.

VRS Exhaust is a good place to look for your tubing. Get a good muffler. IDK of any 3" Twin-Loops, but if you want to keep it quiet as possible, run 2 resonators.

More info??

I've always ran 2.5 inch with no problems. I could never find a place to buy 3 inch when I had my turbo setup either.

plenty of "dyno" sheets as everyone wants to prove the 3'' is a better exhaust setup for most NA setups..

I have two customers "built" d series motors that we are running a 3'' exhaust on.. one is NA with nitrous, the other is a stout NA setup..

I do suggest for smaller motors like d series to start @ 2.5''..

plenty of bone stock b16's have outperformed with a 3'' vs a 2.5

i just bought a ef hatch today with a stock b16a today so im not sure what size the tubing is i think its 2.5 but it goes to a magnaflow and dont know about resonaters and it is quiet cruizing down the freeway from vancouver to salem and it is quiet till vtec hits then it screams

I have myself an ws2 running on 2 1/2 power is not a problem man if u go 3" there's not gonna b any bacc pressure n that can cause to loose torque so better off keeping it Im running a b20b vtec n still made 205hp with that set up...so reconsider

DDTECH

You, never want back pressure.. this is a common myth that's spread over throughout the years. You want more velocity flow.

205, is not alot.. for a b20vtec..its actually on the real low side, and would put money you'd probably break 212-215 with a "real" 3'' vs your crappy ws2.

teg_racer

i put the link up there where we discussed "in detail" about back pressure and how exhausts should be made... some ppl dont care to learn i suppose

eh3 devon

thanks for all the info. i was thinking of the vibrant, or maybe a magnaflow.

i feel as if my ws2 is restricting me, espically in top end if that makes sense. . . and with a 3 inch my motor would flow alott better, i have a stock bore itr with S2 valvetrain and S2 tuner 2 cams, tuned on e85 CTR pistons, RMF replica Header with 2.5 collector. . .

maybe a 3IN piping to my ws2 would make a difference in power? idk lol i doubt it tho, i really love the ws2 lol

been thinking about the Vibrant not sure what im going to do yet

turtleman321

Did you read? Get an 80mm ws2 universal muffler.
