BMW’s M 135i is a potent vehicle in standard trim. Even the best can be further improved. This is where the Scorpion development engineers come into it. The dedicated, highly skilled team have designed a Cat Back system finished with 2x 90mm Daytona tailpipes.

This is also available with the option of either a Sports Catalyst or a Catalyst replacement pipe. When fitted with the Sports Catalyst the power gains are impressive (+14.1 bhp) The weight reduction is even more impressive, shedding a massive 15.5 kg!
