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 M135i Non-Resonated Cat-Back Exhaust System for BMW’s F20 & F21 M135i is the perfect way to add performance and release the N55 engine’s true voice.
