i have an 95 240 and i'm planning on doing an exhaust upgrade. will i loose any horse power if i put a 3 inch cat back exhaust on my 240? the only upgrade i have is an intake. I will be upgrading my engine to kat or sr20det next year. how will a 3 inch catback exhaust sound with a stock ka24de?

You won't lose any power, and it will be loud as hell on an NA KA

No, you won't lose any power. Here's a dyno:

and it isn't that loud if you get a system with a real muffler and a resonator.

Wow how many of these questions have we seen. I'm with you Insanity but I can already see another "CNN Crossfire" episode brewing!

OH yeah anyway I have a 3" Apexi N1 and it rocks. I get a little bubbling backfire now and then and it's loud as all hell but gives me great top end with my JWT Cams and Tuned ECU from 4000-7000rpms!!
