Overview

The ZZP AWD/RWD LTG Downpipe is a high-flow exhaust component designed for Cadillac ATS and CTS 2.0L turbo vehicles. Constructed from fully 304 stainless steel with TIG welding, it offers durability and improved performance. This downpipe is a direct replacement for the stock unit, featuring a 400-cell high-flow catalytic converter and a 2.5" exit flange. It provides typical gains of 10-20whp and quicker turbo spool.
Show original supplier description
The ZZP AWD/RWD LTG Downpipe is ZZPerformance's premier exhaust upgrade for the Cadillac ATS and CTS 2.0L turbo models. Engineered from robust 304 stainless steel and finished with precision TIG welding, this downpipe is built to exceed the lifespan of the vehicle itself. It features a 400-cell high-flow catalytic converter designed to be EPA certified, though it does not meet CARB standards. The pipe includes a 2.5" exit flange and is significantly lighter than the stock component, weighing in at 7.2 lbs compared to the stock 13.5 lbs. Significant performance enhancements are expected, with typical gains ranging from 10-20 wheel horsepower and a noticeable improvement in turbo spool response. Tuning is recommended to maximize the benefits of this exhaust modification. The revised design from 02/2020 addresses rear O2 sensor placement to prevent interference with transmission lines, and it includes a 90-degree spacer for optimal sensor positioning. This downpipe is specifically designed for AWD/RWD 2.0L LTG vehicles including the Cadillac ATS and CTS, as well as the Camaro. It explicitly does NOT fit the Regal or Malibu; a separate FWD version is available for those models.
