Overview

The ZZPerformance downpipe is a high-flow catted exhaust component designed for 2.0L LTG engines. Constructed from 304 stainless steel with TIG-welded seams, this unit offers a significant weight reduction over the factory part to improve turbo response.
Show original supplier description
The ZZPerformance downpipe serves as a performance-oriented replacement for the factory exhaust component, utilizing a 400-cell catalytic converter to increase exhaust flow and encourage faster turbo spool. Compatibility is strictly limited to AWD and RWD versions of the 2.0L LTG platform, specifically the ATS, CTS, and Camaro. This component does NOT fit Regal or Malibu models; a separate FWD version is required for those vehicles. Tuning is recommended following the installation of this part. This downpipe features a revised rear oxygen sensor placement to eliminate potential transmission line interference and includes a 90-degree spacer for optimal sensor positioning. While these high-flow catalytic converters are EPA certified, they do not meet CARB standards. Professional installation is supported by available digital instructions.
