I have a cat back on the way, so i wanna put it on all at once since im gonna be down there. Also, if i get a downpipe will that eliminate the cat converter? If not is there a downpipe that will not eliminate it. Cause i kind of need it when emissions time comes around...

Thanks guys!

i would recomend getting a high flow cat to put on. jc whitney sells 3inch inlet/outlet high flow cats for 139 i think. you can just get whatever exhaust and cut out some of the straight section and clamp the cat in place of it.

So if i get the high flow cat converter...I can have all three? I can have the catback, the cat, and the downpipe?

Yep just look for a downpipe that does not eliminate the cat. Most of them dont anyways.
