Catted Downpipe 2.5" Mandrel-Bent

The CNT Racing Mini Cooper catted downpipe is engineered for R55, R56, R57, R58, R59, and R60 models, offering an upgrade over the stock exhaust system. This component features a metallic high-flow cat, quality welding throughout, and a straight-flow, mandrel-bent 2.5" piping. The design focuses on reducing back-pressure to increase top-end performance and enhance an aggressive high-RPM sound. It incorporates 100-cell custom high-flow metal substrate catalytic converters and is designed for a 100% direct bolt-on installation, utilizing factory ball joints and clamps. Installation requires the removal of the lower heat shield and the bottom bolts of the upper shield. Please be aware that due to replacing the factory catalytic converter, this part may not be legal in all states, may cause a check engine light, and will not pass emissions. It cannot be returned for these reasons. Furthermore, this downpipe is not for sale in California, New York, and Maine.
