3" Regal Catback Exhaust

Exhaust - 3" Regal Catback Exhaust
Exhaust - 3" Regal Catback Exhaust

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 note:

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.

Worth every penny

Overall I’m definitely happy with it. It’s very audible in the car at every rpm, not deafeningly loud but you can definitely hear it. Fitment was a 9/10, one of the pipes fit a little looser than the other and there is a small leak there. Not sure if that’s the fault of the pipe or the clamp but the other one doesn’t leak, either way it’s loud enough that you can’t really tell. Took a little tweaking of the hangers to get it to fit the best but that’s to be expected

Grab some earplugs...

What an exhaust! Honestly it's loud as **** so if that's what you want then man this is for you. For me personally I love music and really getting every bit of it so the exhaust sometimes interferes espesially when driving and the engine is running at about 2Krpms it's deafening lol. Otherwise looks sick, sounds sick, feels a bit better as far as power but it's hard to really tell with all that squat in the rear when accelerating.

Worth it

It was absolutely worth it. It is such a high quality and welds look amazing. It also sounds super good and was quick and easy to install.

Great Exhaust

Great exhaust system, bolted right up as designed. Good fit not perfect but no complaints. Good exhaust note with slight drone, but once again no complaints. I love ZZP and have used them for years, when I need a part for a w-body this is my first stop.
