Show original supplier description
The PLM catted downpipe is engineered to enhance the exhaust flow and turbo performance of the 2023-2025 Toyota GR Corolla. This component utilizes 3-inch precision CNC mandrel-bent 304 stainless steel tubing and features hand TIG welds for superior durability and strength. The integrated 400-cell metallic high-flow catalytic converter is EPA-compliant for OBD2 use on 1996 and newer vehicles, maintaining emissions functionality while significantly reducing backpressure compared to the stock restrictive setup. Designed as a direct bolt-on upgrade, the downpipe integrates seamlessly with your factory exhaust system and includes the necessary installation hardware. It features a 4-inch connection at the turbo outlet to ensure optimal exhaust gas transition. Please note that this part does not fit 2025 models equipped with an automatic transmission. Installation of this downpipe may require an O2 sensor adapter to prevent potential check engine lights if the vehicle has not been professionally tuned. While the component is EPA-compliant, it is not for use in California or areas subject to CARB emissions standards. Always verify your local and state emissions regulations prior to purchase and installation.
