What exhaust would be better

damdog05 · 02-26-2007, 11:32 PM

i believe ive read somewhre that you can put a 3" exhaust on an n/a, but you dont want any larger than that or you start hurting your performance. and thinking back on what ive read about most other peopls cars, more people stick with a 2.5" rather than go bigger. but thats just on the n/a. on another note, i only have one cat on my car and it passes emission here in atlanta. i think as long as they look under your car and see a cat youll be fine.

ok. yeah, thats what my friend said who works at advanced auto parts...since its so old they dont check emissions really, they jsut check for a cat. thats good in my case, i want free flowing =P

georgia and new york arent that different i think...altho NY is a little stricter. thanks for the info!
