This is our 3 chambered quiet resonator for people who already own our catback exhaust system and want a resonator to clamp it into the existing system. If you are handy and can weld yourself please look at our resonator in the other section. This can allow you to run your car with or without the resonator within a few minutes.

This is fabricated with the flange and bend just like your old style resonator or non resonated catback exhaust piece where you would simply un-clamp 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 for the 3800 Series II Wbody's, but still have a nice sound of power when you get on the throttle.

This is for the ZZP dual muffler catback's we offer. This will not bolt into the single exhaust Regal catback.

Choose from the drop downs for 3" or 2.5". All the 3" ones will have a 3" inlet flange and all of the 2.5" ones will have a 2.5" inlet flange. This will only work if you installed our catback using the band clamps we supply.

Love It!

I originally ordered the 3" resonator. After seeing it up close I wondered," What was I thinking?" It was a breeze to return it and order the 2 1/2 " resonator. My car already has a SLP cat back system so this resonator was a simple installation. When I started my car the difference was noticeable immediately. I love the sound of my exhaust because it is not too loud and annoying while driving. This resonator is very quiet. It is exactly what I wanted.

A must

This really tones down the exhaust quite a bit. Very well made. I have zero complaints on it. Thanks ZZP

SS resonator cat back

This product is a high quality item at reasonable price. I would recommend it to anyone needing their resonator replaced.
