I have a 2006 SS/SC and I am looking to replace the exhaust. I have to replace the cat and I am thinking that while I have to do that I might as well do the whole exhaust. So I am looking at the ZZP 2.5" Down pipe w California Cat and the 2.5" Cat back system(currently out of stock) or the 3" Down pipe and 3" Cat back system.

My question is which of these systems would work the best on my stock SS/SC. It only has a K&N Typhoon Air Filter.

Also I emailed the customer service at ZZP to inquire how long before they expect to have more 2.5" cat back systems in stock. I did not receive a reply.


Thanks for your time,

Brian

 

Either one imo. I installed a zzp 2.5 off road pipe and am really happy with it. Car is stock besides injen Cai.

 

3 in catted downpipe and 2.5 inch catback for the best sound. 3 inch catback will be loud on a supercharged car.

 

Will 3" DP bolt right to the 2.5 Cat back or am I going to have to modify it?
