2,5" exhaust to 3"? thoughts
Does anyone have experience of replacing 2,5" exhaust to 3" how much should I expect to get more hp? My mods at the moment:
-RB street port
-To4B (P-trim A/R 1,15)
-HKS F-con + GCC
-720 cc sec. and prim.
-air filter
-93 intake and throttle body
-custom IC (front)
Im using only 12 psi boost pressure because I dont want to break my engine.
(Ive heard that you shouldnt raise your boost pressure more than 12 psi for reliability reasons!?? )

Hey, do some searching... it will help you out alot.
3 inch will probably get you more HP less restricition, turbo spools up faster. If you make sure your fuel system can handle the boost you should be fine!
But do some more reasearch.. for i'm not totally sure...

I think it would help you alot
with four 720's and the f-con. with proper tuning you could be running 15psi I'm sure. and probably hitting close to 300-350RWHP...
you'll need to find a dyno with a wide band o2 to do the tunning.
you'll also want a bigger fuel pump if you don't already have one.
the 12 psi for reliability is for stock IC, stock turbo, and stock injectors.
