This is ZZP’s first exhaust part that we released for the Cadillac ATS and CTS 2.0 turbo.  This is the same part that is installed on Matt’s car which is the worlds fastest stock turbo ATS - we run what we sell. It is fully 304 stainless steel, so it will outlast the car and don’t forget the amazing TIG welding that ZZP is known for. Typical gains are from 10-20whp and quicker turbo spool. Tuning is recommended, and it bolts in place of the stock piece. The stock downpipe is 13.5 lbs, while ZZP's catted pipe is 7.2 lbs.

We are currently offering $125 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. 

Revised 02/2020 with change of rear O2 placement to avoid any transmission line interference. Downpipe now includes 90* spacer for optimal sensor placement. 

Fits the following 2.0L LTG vehicles: AWD/RWD: ATS & CTS, & Camaro.
Does NOT fit Regal or Malibu, however we do offer the FWD version here: FWD LTG Downpipe/ O2 Housing

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.
