ZZP is proud to bring you the first full production, direct bolt on catted downpipes for your LF3 powered CTS V-Sport. Back in 2018 we introduced our H-pipe style downpipe for the ATS-V. Those crossover style downpipes were received with great regard, were the best sounding on the market, and were so good all of our subsequent competitors copied our design. After many requests, we have now brought that same innovation to the LF3 platform. No adapters are needed with our downpipes, just remove your stock pipes and bolt ours in. 

We are offering our V-Sport downpipes in two different configurations; standard and crossover. The standard version is two downpipes running independently of each other. The crossover version is the two downpipes connected with a balance pipe. The reason we offer two variants is to help eliminate that nasty rasp that the LF3 V6 engine commonly produces.

If you are planning on running our CTS V-sport catback then you'll want to purchase the standard version. The patented x-pipe in our catback eliminates the rasp. If you are planning on keeping your stock catback then you will want to purchase the crossover version. Both versions of the downpipe fit all configurations, so whichever version you choose will be compatible with any cat-back setup down the road.

Buying from ZZPerformance is an investment into the platforms innovation. Our pipes are US sourced 304 stainless steel, as well as engineered, designed, and manufactured in our Wyoming MI facilities by U.S. welders and have a 2 year warranty.

Pair our downpipes with our ZZP catback to achieve the perfect sound, tone, and volume on your CTS V-Sport without sacrificing any flow. 

Includes all necessary hardware for installation. Gaskets sold separately. 

Our high flow catalytic converters are EPA certified. If your state requires CARB compliance, these do not meet that CARB standard. Please contact customerservice@zzperformance.com if you have any questions.

We are currently offering $200 in store credit to purchase your stock catalytic converter back from you. If you're interested, take a photo of your stock downpipe and email it to Henry@zzperformance.com. We will provide prepaid shipping labels for domestic (U.S.) shipments.
