Does this fit my car?

This product is compatible with the following models and year ranges:

BMW M135i F40 (2019-2024)

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 3in/76.2mm pipework and fits from the front catalyst section backwards (Cat-back) replacing the PPF, 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). 

Fitment is for motorsport and off road use only as this system removes the PPF filter. 

Please Note:

This 'Valved' exhaust retains the use of exhaust valves. When switching drive modes (e.g. Eco to Race 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.

All relevant fittings and gaskets are supplied.

The product images shown are for illustration purposes only and due to product enhancement may not be an exact representation of the product.

EML lights may activate after removing the standard O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.

Cobra Sport accepts no responsibility for the use of parts which remove emissions devices on the public highway. It is the customers responsibility to ensure that all local laws are adhered to within their home state/country.
