Upgrade the exhaust flow and sound of your BMW or MINI B48-powered vehicle with the DCE Parts B48 Downpipe. Designed for a wide range of BMW and MINI applications, this downpipe is available in multiple configurations to suit different performance and exhaust-flow requirements.

Replacing the factory downpipe with a larger, less restrictive design can help reduce exhaust backpressure and allow the turbocharger to spool more efficiently. Depending on the vehicle configuration and supporting modifications, a downpipe may also improve throttle response, turbo response, and exhaust sound.

• High-Flow Catalytic Converter: Available with a 200-cell sport metallic catalytic converter for a more emissions-conscious configuration.
