hey guys i know youve probably been asked this alot but i was wondering what the best catback system for my car would be. dont care about sound or price as long as it provides the best gains.

 

I believe the APEXi WSII would be a good choice, if you want the best gains period and don't have emissions testing then a straight pipe from the cat would probably be the best for gains.

 

a strait pipe would cause alot less back pressure and there will no low end but more high end

 

k thanks guys and that part would perform well with dc sports header? any sites you would recomend buying from?

 

This has been discussed numerous times. Use the search function to save alot of us from the annoyance!
Just a friendly reminder!

You can always get a custom catback welded up as well. And any exhaust will work fine w/ the headers!
