Scorpion Exhausts OPF-Back System for F20/F21 M140i w/OPF.

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 M140i OPF-Back Exhaust System for BMW’s F20 & F21 M140i is the perfect way to add performance and release the B58 engine’s true voice. It also retains the factory valve setup (all you have to do is carry the motor across from the original exhaust) so that volume can be changed from quiet to loud. It also saves over 4.5kg compared to the standard system. Available with either polished Daytona tailpipes or carbon fibre Ascari tailpipes. Choose in the options.

Fits all OPF-equipped (July 2018 onwards build date) M140is – requires cutting of the original system. Combine with the Scorpion M140i OPF Delete for a cat-back system which does not require cutting. For a full exhaust system, combine the cat-back system with a Scorpion De-Cat Downpipe.

• 80mm (3.15″) diameter pipework
• Dual 100mm tailpipes (Ascari/Daytona)
