ZZP ATS-V Dual 3 Inch Stainless Steel Catback Exhaust

ZZP has always innovated the best products for our markets and we have always been recognized as the innovative company. In the ATSV market, ZZP solved the problem no one else could. Producing an H-pipe that was cost effective and nearly the V6 rasp. No other product, despite many attempts, did this. In fact, the ZZP product was so effective, the design was largely copied by the other vendors in this market. Design work is expensive and ZZP did not even get to recoup our development cost on that product. 

Now ZZP is releasing something even more groundbreaking. A catback exhaust that makes your GM V6 sound like a super car. This product is so unique, special, and achieves what no one else has done since this vehicle has been released. We have therefore taken the unusual step of patenting our design and we will be legally pursuing anyone copying our design in theory or in practice. We hope this is appreciated. Revenue from the sale of our innovations allow us to continue to develop and push the platform forward.

This is a full cat-back system. All cat-backs will come with stainless steel brace in between mufflers. Photos may be of pre-production units without brace. Fits with stock downpipes, ZZP downpipes, and other vendors. 

Valved Version- It splits into two pipes that flow between the straight through ECM controlled valved tip and the 2.5" mufflers.  This makes it nearly as quiet as stock when the valves are shut and loud at WOT.  "Wide Open Throttle".  You will reuse your stock valve motor to retain use of stock valve control via driving modes. 

Currently ships in 1 to 2 weeks.

Update 12.1.2021: Valve actuators revised with spring to reduce valve chatter. If you purchased an ATS-V valved catback prior to 11.29.21 please reach out to and we can provide the updated springs free of charge.

Ats-V Valved Exhaust

if you've watched ZZP videos , you know they say the stock exhaust sounds quite good with their down pipes and intake . but THIS exhaust takes it to the next level . what an insane sound this car makes . putting this exhaust on is super easy, but I can't get over the difference in sound, it's like it added 6 more cylinders to the exhaust note :) that being said, the shift points are off quite a bit and will need a new tune, thus assumed when purchased . AWESOME AWESOME AWESOME

Send it ( a few gripes )

Valves aren't the best quality. Tips stick out a decent amount. Description doesn't state that you'll need to use your oem valve motors. Sounds great and was a easy install for the most part. I'd buy again just because I really enjoy the sound. Welds were good and the steel is USA

Great sound, but….

The install was simple and all aligned. Its sound great, a bit better than the borla catback i used to have. Only 2 problems i have is the flex pipes never the catalyst converters are a bit low causing them to scrap on high speed bumps if not careful. 2nd, the active exhaust valves rattle a bit under cold starting, but goes away after a few seconds. Love the catback system, ill give it an overall 8.5/10.

ATS-V Valved Catback

First off fit and finish were perfect. Install was easy as well. With valves closed exhaust sounds like factory sport mode. Open valves sounds perfect louder than stock but not ridiculous. The exhaust has no rasp or drone. Gets rid of the “gm v6” sound and gives it a more import/exotic exhaust note. I highly recommend this for all ATS-V owners.
