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 and the off-road pipe weigh in at only 5.4 lbs!

When a catted one is ordered we use a premium 400 cell cat which should not set off any check engine lights.  If you select the offroad downpipe then it will set a CEL until the codes are removed from the ECM file.

NOTE: Due to variations in fitment between different year/make/model cars and various transmission options, it is important to verify proper transmission line clearance. Failure to do so may cause the line to rub on the downpipe and cause a leak over time. It may be necessary to gently bend the line by hand to gain adequate clearance. 

Our downpipe now comes with 2 secondary O2 bungs at the bottom of the pipe. This is so the installer can choose which hole will best work for your year/make/model and the clearances with the transmission lines. 

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