LTG AWD/RWD Downpipe

The ZZP AWD/RWD LTG Downpipe is ZZP's first exhaust component for the Cadillac ATS and CTS 2.0 turbo, and is the same part used on the world's fastest stock turbo ATS. Constructed from durable 304 stainless steel with signature ZZP TIG welding, this downpipe is built to outlast the vehicle. This downpipe provides significant performance improvements, with typical gains ranging from 10-20 wheel horsepower and faster turbo spool. The stock downpipe weighs 13.5 lbs, while the ZZP catted version is 7.2 lbs. Revised in 02/2020, the rear O2 sensor placement has been adjusted to prevent transmission line interference, and a 90-degree spacer is included for optimal sensor positioning. Tuning is recommended, and the downpipe bolts directly in place of the stock unit. This downpipe fits the following 2.0L LTG vehicles: AWD/RWD ATS, CTS, and Camaro. It does NOT fit Regal or Malibu models; a FWD version is available separately. The high-flow catalytic converter is EPA certified but does not meet CARB compliance standards.
