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 eliminated 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. 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 customerservice@zzperformance.com and we can provide the updated springs free of charge.
