BMW M135i (F20 & F21) Performance Exhausts

Our range of BMW M135i sports exhausts has been developed using 3 inch/76.2mm stainless steel pipework for maximum flow and possible power gains. Our performance exhaust systems for the M135i have been developed in cat back exhaust form with the option for a resonated or louder non resonated centre section. To match these sport exhaust systems for the M135i 3.0 litre turbocharged straight-six engine we have developed a de-cat front pipe for motorsport and off road use along with a high flow sports catalyst which will allow you to pass UK MOT emission tests.
