Scorpion GPF Back Exhaust System For BMW F40 M135i xDrive (GPF Model)

The Scorpion GPF-Back Exhaust System for the BMW F40 M135i xDrive (2019–2024, GPF model) is a precision-engineered upgrade designed to enhance sound, improve flow, and reduce weight compared to the stock system. Built from 70mm (2.75”) T304 stainless steel mandrel-bent pipework, it provides optimised exhaust gas flow, sharper throttle response, and Scorpion’s distinctive performance tone.

This system retains the factory valve control, requiring the OE motor for operation, and integrates seamlessly with both OEM and Scorpion components. Please note, the original exhaust requires cutting for installation unless paired with Scorpion’s SBMP083 section.

To allow personalisation, this system is available with five premium tailpipe finish options:

• SBM083 – Polished 114mm Daytona Tailpipes

• SBM083I – Polished 114mm Indy Tailpipes

• SBM083C – Black Ceramic 114mm Daytona Tailpipes
