Scorpion Exhaust High Flow Sports Cat Downpipe For BMW M135i xDrive F40 (GPF Model)

The Scorpion Exhaust High Flow Sports Cat Downpipe (SBMX083) for the BMW M135i xDrive F40 (GPF model) is a precision-engineered upgrade designed to replace the restrictive OEM catalyst with a high-flow sports catalyst. By increasing exhaust gas flow, this downpipe reduces back pressure, sharpens throttle response, and delivers significant performance gains while enhancing the exhaust tone of BMW’s 2.0-litre turbocharged engine.

Crafted in the UK from T304 motorsport-grade stainless steel, this downpipe features a large 70mm (2.75”) mandrel-bent design for optimised flow and long-term durability. Designed to integrate seamlessly with both OEM and Scorpion exhaust systems, it ensures straightforward installation and perfect alignment. The high-flow catalyst also helps maintain emissions control while unlocking the full potential of the B48 engine.
