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.
Press Release
The third generation of BMW’s 1 Series was launched in 2019, with the chassis name F40. For the performance range topping F40, BMW revived the ‘M135i’ moniker, sporting BMW’s B48 2 litre, 4-cylinder engine. The M135i is shipped from the factory with a muted exhaust sound leading to a very disappointing driving experience. Along with increased performance, Cobra Sport were keen to put the emotion back into the drive with an improved aural and emotional driving experience.
Cobra Sport opted for 3”/76.2mm stainless steel pipework for the biggest upgrade in terms of performance, flow rate and sound levels. The free-flowing Cobra Sport exhaust setup completely transforms the vehicle and will open up the future tuning possibilities of the BMW M135i (F40).
Cobra Sport have transformed the styling of the BMW M135i, creating a quad exit conversion that draws attention to the peachy rear of BMW's hot hatch. With 4" (101.6mm) carbon fibre quad tips specifically selected to ensure you stand out from the crowd and draw attention to the looks as well as the sound of your M135i.
The all-new GPF/PPF-Back quad exit performance exhaust with rear silencer perfectly compliments the 'jack of all trades' character of the M135i. In comfort mode the exhaust valve is closed, allowing the driver to cruise around and eat up the miles in comfort, with just a subtle hint that there is over 300BHP available at the press of the right foot.
Switch to Sport mode and the drive of the M135i is transformed, the exhaust valve opens allowing exhaust gases to be split between the rear silencer and a rear silencer by-pass, enhancing the exhaust sound levels and allowing the M135i to sing to its hearts content and recording 91dB at 4,000rpm, an increase of +11.1dB - capturing the motorsport heritage that runs through the veins of the M135i.
Cobra Sport has also developed their race box delete performance exhaust for the ultimate thrill seeker. This system takes inspiration from Cobra Sport's venom range by removing the rear silencer and exhaust valves, the race box delete allows for the biggest upgrade in terms of sound levels recording 92.8dB at 4000RPM (+12.9dB) at all times - whilst keeping the factory fit catalyst and GPF (gasoline particulate filter) in place.
