i'm building b16a2 turbo and i ordered 3" muffler and they send me 2.5 on inlet side, i have
b16a2
ctr cams and springs
holset HY35
3" DP
3" exhoust
msd ignition etc.
my power goal is 400 and my question is - is it sens to use this 2.5 muffler when everything else is 3? will that effect my power goal?

or sell this one and buy 3?

 

sell it and buy a 3". the 2.5 is just gonna become a bottleneck.

 

Sell it, you are just going to lose power with the 2.5 muffler.

 

why run a muff at all man my car is quiter now without one on the trubo than it ever was on a fart can lol

 

i like quiet so i want muffler

 

do you still have piping all the way back or is it open downpipe

 

Nah, i'd ditch the 2.5in exhaust and go ATLEAST 3in. 2.5in js don't cut it anymore. i'm selling my 3in Thermal R&D exhaust. in very good shape. fits all EK models if interested. in lots of ppl's opinions, it's the best 3in. exhaust ever made. Js make me an offer if interested. I'm gunna post it on here and hope it sells. GL with the exhaust and setup.

 

More inches=better. C'mon, everyone knows that =/

 

I make decent power with my 2.5 but if i go to 3in I'll just ruin the piping. Reason being my car so low so I can't go any bigger without raising the car. Then again I run an open downpipe
