Show original supplier description
The ZZP AWD/RWD LTG Downpipe is a performance exhaust upgrade for Cadillac ATS and CTS models, as well as the Chevrolet Camaro equipped with the 2.0L LTG engine. It directly replaces the stock downpipe, contributing to increased horsepower and quicker turbo spool. This downpipe is designed to provide significant performance enhancements, with typical gains ranging from 10-20 wheel horsepower. It also offers a weight reduction, with the catted version weighing 7.2 lbs compared to the stock downpipe's 13.5 lbs. Tuning is recommended to maximize the benefits of this upgrade. The manufacturer states that the rear O2 sensor placement was revised in 02/2020 to prevent interference with transmission lines, and the downpipe now includes a 90-degree spacer for optimal sensor positioning. This ZZP downpipe is compatible with AWD/RWD variants of the ATS, CTS, and Camaro. It specifically states that it does NOT fit the Regal or Malibu models; a separate FWD version is available for those vehicles. The high-flow catalytic converters are EPA certified but do not meet CARB compliance standards, which may be a consideration depending on local regulations.
