Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality.
This BMW M135i performance exhaust is made in 3"/76.2mm pipework and fit from the turbo backwards (turbo-back system), these parts replace the front pipe, centre and rear sections.
The resonated exhaust includes the centre silencer and has a subtle but sporty tone. This exhaust however, is also available as a non-resonated version which is a louder option as it excludes the centre silencer and therefore, has a sportier exhaust note.

Please Note:
The 'Valved' exhaust retains the use of exhaust valves. When switching drive modes (e.g. Eco to Sport mode) your exhaust tone will continue to swap from quieter to louder tones as before.
The 'Non-Valved' exhaust removes the use of exhaust valves. When switching drive modes (e.g. Eco to Sport mode) your exhaust tone will not change from quieter to louder as before. Using a Non-Valved exhaust will not harm the running of your vehicle, you will simply not have exhaust sound options, however the Cobra Sport exhaust has been designed with this in mind.
IMPORTANT: this exhaust removes the PPF filter and will require engine tuning at time of fitment to cancel the EML light.
Fitment is for motorsport and off road use only as this system removes the PPF filter.
Fitted images show the non-valved resonated version.
