as the topic says

 

i'm curious also cuz i have an apexi WS cat back

 

I put down 240 WHP and 230 Ft-LB on a B20 @ 10 PSI with 2.25 Exhaust (With a 1.75inch Bottleneck where the downpipe mates up to my test pipe)

 

E-Cutout!

 

326 hp and 226 tq@ 12 psi stock internals and 2.5 in down pipe, CAT and 2.25 in crush bent piping lol

 

check sig. 2.5 DP to 2.5 cat to greddy evo

 

how loud is your 2.25 exhaust? is it real noticable from far

 

The numbers in my sig were on 2.25" Apex dunk exhaust. No cat and 3" dp.

That is really good! I was gonna shoot for those numbers after the full 3 inch and some internals! Right now I will be happy with 250...very happy with 275.
