BMW M135i (F40) Performance Exhausts

Our range of BMW M135i (F40) sports exhausts have been developed using 3 inch/76.2mm stainless steel pipework for maximum flow and possible power gains. Our performance exhaust systems for the M135i is available in with a standard twin tailpipe or quad tailpipe upgrade in GPF back and 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 we have developed a de-cat front downpipe for motorsport and off road use along with a high flow sports catalyst which will allow you to pass UK MOT emission tests.

Entering the market with big boots to fill, the M135i had its work cut out replacing its older brother. BMWs change of recipe certainly had some heads scratching in the auto market as BMW release a hot hatch more in keeping with its immediate rivals. Performance, style, and sound are often at the forefront of a BMW owners mind and drivers of the new M135i are no exception.

The M135's 2 litre turbocharged engine lacks the audible emotion of its predecessor with GPF filters to further aid emissions regulations and dampen sound levels. Cobra Sport’s performance exhaust system is here to balance the equation enabling owners to maximise the drive of their M-lite. If style and sound are your only requirements, Cobra Sport’s GPF back system will ensure your M135i sounds as it should from factory.

Cat-back and turbo back systems are available for those looking to extract the most from their M135i whether that be for track or off road use.

All Cobra Sport performance exhausts are hand made in Sheffield and showcase mandrel bent certified grade 304 stainless steel pipework, formed by superior TIG welding techniques ensuring a quality finish that we guarantee for a lifetime.
