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. 

Rear Section Options:

Non-Valved Version- It comes with 2 straight through 3 inch mufflers and eliminates GM's active muffler system. These systems are made to order and should be shipping within 2-4 weeks. 

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". These systems are made to order and should be shipping within 3-6 weeks.

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.
