As the official technical partner to the Airwaves BMW BTCC team, Scorpion knows exactly how to extract the best performance from high performance BMW engines.

The Scorpion B58 Sports Cat downpipe optimises exhaust flow by replacing the highly-restrictive factory catalytic converter, and also adds to the aural experience. This is one of the best upgrades you can make to allow the B58 engine to truly perform in your F2X M140i/M240i or F3X 340i/440i.

These pipes bolt directly to the OEM system and use factory mounting locations. Not suitable for OPF models (July 2018 onwards) without an OPF delete.

• 100mm (4″) diameter
• 3.1kg saving over original downpipe
