Ok right now I have badmab short headers and a 3" catted zzp DP with a 2.5 exit installed. I got the 2.5 so it would fit to the stock catback. Im ready to get a catback now tho and i wanna know should i get a 2.5 catback or get the zzp 3" with the 2.5 hookup.

 

bump

 

Ive heard people say its pointless to go 3 inch unless your going turbo or TVS.

 

dont go bigger then 2.5 unless you go tvs.

 

If you get the 3 inch ZZP exhaust we will have the exact same set-up, heres what mine sounds like

YouTube - Full exhaust! Bad-mab shorty header installed!
YouTube - Cobalt SS/SC Fly-by

 

I have no plans for tvs or turbo, iv just heard so many different things about 2.5 vs 3 for the sc and i also didnt know if it was pointless to have a 3" catback because it would be 2.5 where the dp and catback connect since the dp is a 3" with a 2.5 exit. ill stick with a 2.5 then anyone know a good 2.5 for 500 or less?

 

just go with 2.5 and u will be fine

 

Epic U-Turn fail. Sounds good though. I like it
