Exhaust q's

[myk]

For my h22 I was thinking of just getting a catback like the apexi ws2 kit and a hi flow cat, I was wondering if there would be any significant difference if I got a full custom 2.5' exhaust, or shoud I get the cat back and a larger diameter downpipe? would that be the around the same?

if your h22 Id get the apexi worlds sport. Great product. Then again 2.5 in piping all the way through custom bent or whatever would be good. Bigger dp will help.

eh hope this helps

Get a header mod it to a 2.5" collector and 2.5" piping back with your choice of muffler ta daa theres a good exhaust system there. And its cheaper than most aftermarket companies but you can purchase those if you want they are pretty good. I think the 2.5" might gain a lil more but you never know it depends.
