Hey guys, so I'm in the process of saving up to change my entire exhaust system (headers, downpipe, catback) and I just want to know; if I go with Bad Mad headers and a 3" ZZP downpipe with a 3" or 2.5" exit, what would be the best catback system to go with? I really don't want to spend over $400 on the catback considering the headers and downpipe are costly on their own haha.

 

Get 2.5" downpipe.

Theres a guy selling a 2.5" ZZP catback. Get that.

 

The Bad-Mab header has a 3 inch exit right? I think he should go all 3 inch if thats the case, because it's never good to start out large and go small. It's around $509 for the ZZP 3 inch cat-back. Around a hundred dollars more for a lot less restriction, sounds good to me. And just because the 3 inch dnpipe and exhaust is more beneficial for turbo balts doesn't mean it doesn't help if you go for a staged supercharger.

 

Brad at BadMab makes a great product. ZZP DP added as well will make things even better. Enjoy the modding

it would be fine to have a 3" dp and a 2.5" catback.
that would be the ideal exhaust for a mildly moded car...i think..

 

he will end up loosing power with a total 3" system...
a 3" system would be for a 350+ hp car....
2.5 catback will be fine with a 3" dp..
and the car won't be to loud

 

I would like to go gmpp

 

that's fine just more money...
