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. No tuning required, although it 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 use a premium 400 cell cat which should not set off any check engine lights, however when changing any catalytic converter in new cars you run the risk of a P0420 code. 

We are currently offering $100 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 downpipes come with a high flow catalytic converter that is 48 state legal. Our catalytic converters will not pass California or New York state emissions. Please contact customerservice@zzperformance.com if you have any questions.
