ZZP Resonator Section for Catback

*This product is made to order- expect delayed shipping*

This is our 3 chambered quiet resonator for those who already have our catback exhaust system and want to clamp it into your existing system. Choose from the drop downs for 3" or 2.5". The 3" option will have a 3" bolt in flange and a 3" exit (intended for our 3" catback). The 2.5" option will have a 2.5" bolt in flange and a 2.5" exit (intended for our 3" catback).

If you are handy and can weld yourself please look at our resonator in the other section. This specific product is fabbed with the flange like your old style resonator or non resonated catback exhaust piece where you would simply unclamp and remove your old pipe and replace that entire section with this section.

This will by far reduce the loudness and droning while cruising that is common on naturally aspirated or supercharged Cobalts and Redlines, but still have a nice sound of power when you get on the throttle.

This is made to bolt up to our ZZP catback exhaust systems. This will not bolt up to a different brand exhaust or stock exhaust.

Tame that exhaust

I added this after installing my new system. Quite frankly the exhaust was too loud without it. I believe race cars should be loud and street cars should sound good. If you like to listen to music you need the system with a resonator. I didn't notice any change in performance so I'm happy.

Get one if your live in California

The resonator realy hushed my cobalt. The quality of the resonator can not be matched but thats like all of ZZP products hight quality. Didnt want to put one on, but with the new CA law on excessive exhaust nosie its a must especialy after the 3rd ticket. Now i drive next to the cops with no worries.
