INEOS Grenadier B58 Performance Downpipe

Manufactured by Circuit Werks | Optimized for Overland Xtreme Performance Tune

Unlock the full potential of your BMW B58-powered INEOS Grenadier with this high-flow performance downpipe, manufactured by Circuit Werks and specifically selected to complement the Overland Xtreme performance tune.

By eliminating the factory catalytic restriction, this downpipe significantly reduces exhaust backpressure, allowing exhaust gases to flow more freely. The result is improved turbo efficiency, quicker spool, sharper throttle response, and stronger midrange torque throughout the RPM range.

When paired with the Overland Xtreme B58 Performance Tune, this upgrade helps maximize power gains and optimize engine performance under increased boost levels.
