Default Exhaust Help

Hey I was going to get my exhaust done soon and i was wondering is 3inches too big for a stock sc300? i plan to make minor power gains and possibly higher power later on but would 3 inches be bad? should i stick with 2.5?

I'd stick with 2.5" if you are staying n/a but if there is a good chance of boost in your future then go 3".

3" is gonna be loud as hell lol, i have 3" straight pipe to a apexi N1 on my turbo SC and it's really loud..

what Ali said basically sounds like good advice though..


if you run duals it won't be as loud..

i was running 3" catback exhaust when i was n/a but i know i was gonna go turbo eventually. was running open downpipe for a couple of weeks and it was loud as fawk, just dropped my car off at Blue Ridge Motorsports today to get a 3" midpipe made. i'll see how loud it's gonna be compare to open downpipe, hopefully not to loud.
