This is a single 3" cat back that uses our ZZP resonator and muffler that exit in the factory location. It is entirely constructed of stainless steel so it will virtually last forever.

Special notes:

This is a true 3" catback, so it will not bolt up to the factory 2 3/8" outlet downpipe, you will need a 3" exit flange downpipe. We sell a downpipe that will bolt directly to this catback. Please make sure to select 3" exit flange.

If you are looking to purchase our ZZP stage 2 kit this catback will NOT fit. The stage 2 kit comes with a downpipe for your stock exhaust, while this catback requires a 3" exit downpipe. If you have any questions please email [email protected]. 

Fits: 1997-2004 Buick Regal 3.8L
