  • BMW M135i (F40) GPF/PPF Back Race Box Delete Performance Exhaust

    Cobra Sport BMW M135i (F40) GPF/PPF Back Race Box Delete Performance Exhaust

    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 fits from the Gasoline Particulate Filter section backwards (GPF-back) replacing the centre and rear sections. GPF Back with Box Delete Test Results: Sound - Engine at Idle: 73.5dB (+10.5dB) - Static 3,800rpm test: 95.1dB (+13.1dB) All relevant fittings and gaskets are supplied. This exhaust offers a significant improvement in terms of exhaust tone, bass and sound level whilst keeping the stock catalyst and GPF in place. This exhaust has a choice of 4" (101.6mm) tailpipe options including a choice of carbon fibre tip options. Please Note: The '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. The 'Non-Valved' exhaust removes the use of exhaust valves. When switching drive modes (e.g. Eco to Race 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. 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, which had not made an appearance on the back of a Baby BMW since its predecessor, the F20 M135i. Sporting BMW’s B48 2 litre, 4-cylinder engine with Twin Power Turbo technology, the B48 produces 306hp and a thumping 332lb ft of torque. These punchy figures fire the M135i from 0-62MPH in just 4.8 seconds and on to an electronically limited top speed of 155 MPH. 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 experience. Cobra Sport opted for 3”/76.2mm stainless steel pipework which is larger than most on the market 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). During the design stages, Cobra Sport made sure that all of the configurations are interchangeable so that customers can add to their system over the coming years. We imagine most will start with the PPF back configuration which can be fitted without the need for any engine tuning as it keeps the stock catalyst and PPF in place (MOT compliant). Adding a PPF delete section would create the cat back setup and customers going down the tuning route can add a high flow sports catalyst or de-cat front pipe to create a full turbo back setup. For those who want further improve sound levels, Cobra Sport offers their unique rear silencer delete range. This exhaust setup removes the rear silencer to offer the biggest sound increase whilst keeping a sporty exhaust tone (+13.1dB in PPF back rear silencer delete configuration). The Cobra Sport team were able to reduce the weight of the exhaust system by an impressive 49% over the OEM system with the PPF back rear silencer delete system weighing in at only 9.02kg compared to the original 17.8kg. Cobra Sport have improved the styling of the BMW M135i, creating a noticeably enhanced and balanced look to the rear of the M135i with a choice of dual 4” (101.6mm) and 4.5” (114.3mm) slash cut highly polished stainless-steel tailpipes. For those looking to take the style upgrade a stage further, upgraded carbon fibre tailpipes are available. Like all Cobra Sport exhausts, the M135i F40 exhausts are TIG-welded from high-quality T304 stainless steel and the mandrel pipework is a full 3” (76.2mm) in diameter for maximum sound and tuning potential.

    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 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 'non-valved' exhaust removes the use of exhaust valves. 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. All relevant fittings and gaskets are supplied. Maxton Design Rear Valance is not included - please purchase this directly from Maxton Design here. 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.  Media Static Sound Example - Non-Valved GPF Back with Box Delete Static Sound Example - Valved GPF Back with Rear Box Brand Video - Designed to demand attention, engineered to lead.

For the performance range topping F40, BMW revived the ‘M135i’ moniker, which had not made an appearance on the back of a Baby BMW since its predecessor, the F20 M135i. Sporting BMW’s B48 2 litre, 4-cylinder engine with Twin Power Turbo technology, the B48 produces 306hp and a thumping 332lb ft of torque. These punchy figures fire the M135i from 0-62MPH in just 4.8 seconds and on to an electronically limited top speed of 155 MPH. 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 experience. Cobra Sport opted for 3”/76.2mm stainless steel pipework which is larger than most on the market 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). During the design stages, Cobra Sport made sure that all of the configurations are interchangeable so that customers can add to their system over the coming years. We imagine most will start with the PPF back configuration which can be fitted without the need for any engine tuning as it keeps the stock catalyst and PPF in place (MOT compliant). Adding a PPF delete section would create the cat back setup and customers going down the tuning route can add a high flow sports catalyst or de-cat front pipe to create a full turbo back setup. For those who want further improve sound levels, Cobra Sport offers their unique rear silencer delete range. This exhaust setup removes the rear silencer to offer the biggest sound increase whilst keeping a sporty exhaust tone (+13.1dB in PPF back rear silencer delete configuration). The Cobra Sport team were able to reduce the weight of the exhaust system by an impressive 49% over the OEM system with the PPF back rear silencer delete system weighing in at only 9.02kg compared to the original 17.8kg. Cobra Sport have improved the styling of the BMW M135i, creating a noticeably enhanced and balanced look to the rear of the M135i with a choice of dual 4” (101.6mm) and 4.5” (114.3mm) slash cut highly polished stainless-steel tailpipes. For those looking to take the style upgrade a stage further, upgraded carbon fibre tailpipes are available. Like all Cobra Sport exhausts, the M135i F40 exhausts are TIG-welded from high-quality T304 stainless steel and the mandrel pipework is a full 3” (76.2mm) in diameter for maximum sound and tuning potential.
