B58 4.5” Catless Downpipe Norcal Dynamics

Note: Track use only includes warranty

Upgrade from the standard B58 downpipe to the catless Norcal Dynamics B58 downpipe for maximum airflow, performance and sound.

The Norcal Dynamics Catless B58 Downpipe is a must-have upgrade for any BMW enthusiast looking to maximize the performance of their B58 engine. Constructed from premium materials, this downpipe is designed to provide maximum exhaust flow and improve turbo spool time, resulting in increased power and torque.

Our B58 downpipes are constructed from high quality 304 stainless steel that provides excellent durability and corrosion resistance. Catless design eliminates restrictive catalytic converters, allows for maximum exhaust flow and reduces back pressure. This results in a significant increase in power and throttle response and a more aggressive exhaust note, and is designed to be a direct bolt-on replacement for your factory downpipe, making installation quick and easy. And the downpipe is designed to work seamlessly with the factory exhaust system, so you never have to worry about compatibility issues.

Overall, the Norcal Dynamics Catless B58 Downpipe is a must-have upgrade for any BMW B58 engine owner looking to improve performance and maximize their vehicle's potential.
