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 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.

Revised 02/2020 with change of rear O2 placement to avoid any transmission line interference.  

Fits the following LTG vehicles: AWD/RWD: ATS & CTS, & Camaro.
Does NOT fit Regal or Malibu, however the FWD LTG Downpipe/ O2 Housing does.
