Scorpion BMW G01 X3 M40i LCI High Flow Sports Cat Exhaust Downpipe (2021-2025)

The Scorpion high flow sports cat downpipe for the BMW G01 X3 M40i LCI is engineered to improve exhaust flow and response while retaining a catalytic converter for improved usability. Designed specifically for MHEV-equipped LCI models, this downpipe targets the most restrictive section of the factory exhaust system to deliver a more engaging and responsive driving experience.

Featuring a large 125mm (5") pipe diameter, the downpipe allows exhaust gases to exit the turbocharger more efficiently, reducing back pressure and improving flow consistency. The high flow sports catalytic converter strikes a well-judged balance between performance and refinement, delivering a deeper, more purposeful exhaust tone without the abruptness associated with decat setups. Throttle response feels sharper, and the engine breathes more freely across the rev range.

Manufactured from high-quality stainless steel, this Scorpion sports cat downpipe offers excellent durability and heat resistance, alongside a 1.7kg weight saving over the OEM component. Designed to integrate seamlessly with either the factory exhaust or Scorpion systems, it provides flexibility for staged upgrades while maintaining OEM-level fitment.
