I have a 3" pipe with no CAT on KA24DE, all because it came with a 4" tailpipe. The thing is loud as hell.

lol backpressure is bad anyways.there are a few dyno charts floating around that show nothing but gains comparing 2.5 to 3.

so are we saying that the 3" is the way to go ? even for a daily driven car?

Just do it. Gains / losses aren't notcible. If youre planning on keeping it n/a... then theres no need to risk getting a ticket because its loud for no reason. If your planning on boosting it in the future, then don't waste your money on a 2.5"
