BMW F40 M135i - Scorpion GPF-Back system with electronic valve

Upgrade the sound, performance and character of your BMW 1 Series F40 M135i xDrive with the Scorpion GPF-Back Exhaust System, engineered specifically for GPF-equipped models. This premium exhaust system delivers a deeper, sportier exhaust note while improving exhaust flow and reducing overall system weight compared to the factory setup.

Manufactured in the UK from high-grade T304 stainless steel, the Scorpion GPF-Back system replaces the restrictive rear section of the exhaust while retaining the vehicle’s OEM exhaust valve functionality. This allows you to enjoy a refined sound during everyday driving, with a more aggressive tone available when the valves are open under load or in sport modes.

Designed as a direct-fit upgrade, this exhaust system improves throttle response and driving engagement without compromising comfort or drivability, making it ideal for fast road use and enthusiast builds alike.
