The ZZPerformance catback system is the best exhaust money can buy for the LS4 Grand Prix. Constructed of stainless tubing and flanges, the ZZPerformance 2.5" exhaust system will last virtually forever. This also comes with ZZP's exclusive stainless chambered resonator and mufflers.

Can be optioned with the ZZP resonator or without. We highly recommend the resonator for all setups.

Great Product!!

Quality made exhaust and super easy to install. Everything you need is in the kit. Hardest part was taking the old exhaust out. Sounds awesome and the price was the best around!!!

ZZP 2.5” GXP Catback Exhaust

The installation went very well with very few hiccups. They clearly label everything for you, even the different sized exhaust clamps, and it is overall a very high quality exhaust. Although, a nice touch would be a new gasket after the down pipe and some new fasteners. This exhaust comes with new rubber hangers for the mufflers and reuse the factory hangers everywhere else. As for sound, ZZP did an outstanding job. The sound is mostly true to their promotional video, except it is a bit louder than advertised. It isn’t annoying to listen to on the highway or while cruising, but you’ll hear it if you even tap the throttle lightly. Super happy with how it turned out. Great accompanying upgrade alongside a DOD delete.
