Cobra BMW F40 M135i xDrive Turbo Back Performance Exhaust
Transform your BMW F40 M135i xDrive with the Cobra Sport turbo back performance exhaust. Built in 3 inch 76.2 mm pipework from the turbo back, this BMW M135i exhaust system replaces the front pipe, centre and rear sections to unlock a deeper, sportier exhaust note and sharper character. Choose resonated or non-resonated, valved or non-valved, sports cat or de-cat, plus premium tailpipe finishes to perfect the look and sound.
We have fitted this system on customer cars here at Nforcd in Warwickshire and the feedback has been fantastic. Owners love the build quality, fitment and the way it elevates the M135i driving experience.
Why choose the Cobra Sport M135i turbo back exhaust
- 3 inch 76.2 mm turbo back design for maximum flow
- Resonated or non-resonated options to fine-tune volume
- Valved or non-valved configurations for driver-selectable tone or fixed sporty sound
- Sports cat or de-cat front sections for track-focused performance
- Premium tailpipe choices including chrome and carbon fibre
- All relevant fittings and gaskets supplied
- Cobra Sport quality backed by a Lifetime Warranty to the original purchaser
Sound options explained
Resonated includes a centre silencer for a refined yet sporty tone. Non-resonated removes the centre silencer for a louder, more aggressive exhaust note.
Valved systems retain the factory valve control. Changing drive modes will continue to switch between quieter and louder tones. Non-valved systems remove valve control so the tone remains consistent. This will not harm the running of the vehicle.
Tailpipe options
- TP19 - 4.5 inch Chrome Tailpipe
- TP38 - 4 inch Chrome Inverted Tailpipe
- TP106-CF - 4.5 inch Slash Cut Carbon Fibre Tailpipe
- TP107-CF - 4 inch Slash Cut Carbon Fibre Tailpipe
Compatibility
BMW 1 Series F40 2019+ including BMW M135i, M135i xDrive, M135ix.
Important compliance note: Systems that remove the GPF/PPF filter or use a de-cat configuration are for motorsport and off-road use only. A mandatory ECU reflash is required on PPF-equipped models to prevent the EML light.
What’s included
Turbo back system comprising front pipe, centre section and rear section. All relevant fittings and gaskets supplied.
