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 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.

Excellent quality

Easy install, band clamps are so much better than "U" clamps. Nice deep sound, the car breaths so much better, an easy 20+ HP gain at mid rpm range, top end is much better. Have already taken a couple of "sports cars" to the wood shed, gotta love it.

That was easy. Not a Magnaflow, though.

First, I'm most impressed with the fact that this bolted on and "just worked" perfectly with the ZZP 3" downpipe. I've dealt with aftermarket exhaust systems before and frequently there's something that leaks or needs to be bent into shape or rubs on the car or some other needless problem. I am happy to say that this exhaust exhibits none of that. Everything bolted up nicely and while the tip was a little big and show off-y, I've grown to like it. I've had it on the car for a couple of weeks now and in general, I do like the sound. There is NO awful 3800 rasp to speak of and the tone is very mellow, BUT there is an appreciable amount of highway drone. It's not awful, and it's certainly better than many other 3800 exhausts I've heard on Grand Prixs, but it's something to be aware of. Otherwise, I have gotten compliments from people on the sound. It also appears that at some point, ZZP stopped using a Magnaflow muffler. This has some "ZZP" branded muffler, I have no idea who makes it, but it is a straight through design that seems to be a generic MF clone. They really need to edit the item description. A final note is to NOT use the included gasket. Unlike the very nice band clamps they include, the gasket is hot garbage. Throw it away and buy the Remflex 8038 kit, which comes with two 3" gaskets, which I used for both the rear Plog to DP and DP to exhaust flanges. Aside from those minor complaints, I am VERY happy with the exhaust and I'd much rather bolt this on in my driveway than go to an exhaust shop.
