Cobra Sport BMW F40 M135i xDrive Cat Back Exhaust - Venom Race Box Delete

Transform your BMW M135i F40 M135ix with the Cobra Sport Venom Cat Back Race Box Delete performance exhaust. This proven upgrade delivers an aggressive motorsport soundtrack, sharper throttle response feel and stand-out rear-end styling. Built in 3 inch 76.2 mm pipework, it fits from the front catalyst section back and replaces the PPF, centre and rear sections for a free-flowing, high-impact exhaust note.

We have installed this system on customer cars and the feedback has been consistently positive. Fit and finish are excellent, valve operation on valved variants works exactly as you expect, and the Venom box delete unlocks the authentic M135i character enthusiasts are searching for.

Why choose this BMW M135i F40 exhaust

  • Cat back exhaust for BMW M135i F40 M135ix xDrive - fits from the front catalyst back
  • Replaces PPF, centre and rear sections for maximum flow and sound
  • Venom box delete design - rear silencer delete for a race-inspired tone
  • Available as resonated or non-resonated, valved or non-valved to tailor volume and character
  • 3 inch 76.2 mm performance pipework for reduced back pressure
  • Tailpipe options in chrome or carbon fibre to complete the look
  • All required fittings and gaskets supplied
  • Cobra Sport lifetime warranty for peace of mind

Sound options: the resonated versions include a centre silencer for a refined yet sporty tone. Non-resonated versions remove the centre silencer for a louder, harder-edged exhaust note. Valved versions retain factory valve control so tone changes with drive modes. Non-valved versions remove the valve control for a consistent sound profile.

Compatibility

  • BMW 1 Series F40 2019+
  • BMW M135i M135ix xDrive

Important notes

  • This system removes the PPF. A mandatory ECU reflash is required when fitted to PPF models to cancel the EML light.
  • Fitment is for motorsport and off-road use only.
  • Venom box delete systems are designed without a rear silencer and will be loud.

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
