backfire and powerloss....
what would be the downside with having a 3" catback and 2.5" performance cat zzp dp, WITHOUT the header? Thats the setup I got now and it backfires (you can hear it.) and it seems like I lost power, like ALOT.
could it be an exhaust leak? or does it need another good tune? either way im still getting the header.

thanks alot! you have been very helpful. I tore off my 3" catback and put a 2.5" on right quick. because I have a hole bunch of exhaust components just hanging around in my garage.

Unless you are going at least 2.8" pulley or smaller or TVS having a 3" exhaust is going to hurt your low and mid range power. Sure, you might gain a little HP up top but you lose HP and TQ in the low and mid ranges which really isn't helping at all.
