Scorpion Exhausts Non-Resonated Cat-Back System for F22/F23 M235i.

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. It also saves nearly 1kg compared to the standard system, with claimed performance gains of 6.5bhp. Available with either polished Daytona tailpipes or ceramic Daytona tailpipes. Choose in the options.

This system has an in-built valve as with the standard system. The OEM controller can be carried over for a seamless fit. This system will also fit with both the standard and the M Performance valance thanks to adjustable tailpipes.

For a full turbo-back exhaust system, combine the cat-back system with a Scorpion De-Cat Downpipe.
