Requires mandatory ECU reflash when fitted to PPF models. Fitment is for motorsport and off road use only.
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 quad tailpipe exhaust conversion (quad exit / 4 tailpipes) 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.
Once fitted, the new Cobra Sport M135i quad tip exhaust conversion and replacement body panel look entirely at home on the car and gives the M135i a much sportier edge with dynamic sound and improved looks.
This performance exhaust is designed to fit with the addition of the Maxton Design quad exit M3 Style rear valance panel (Please click here to view this product, Maxton Design part code: BM-1-40-MPACK-RS2G).
All relevant fittings and gaskets are supplied.
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.
IMPORTANT: this exhaust removes the PPF filter and will require engine tuning at time of fitment to cancel the EML light.
Maxton Design Rear Valance is not included – please purchase this directly from Maxton Design here.
Fitment is for motorsport and off road use only as this system removes the PPF filter.
