We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply.

BMW F40 M135i xDrive Full System From Turbo To Tailpipes

Give your BMW 1 Series F40 M135i xDrive or M135ix the soundtrack and response it deserves with this complete performance exhaust that runs from the turbo to the tailpipes. Designed for drivers who want a harder-hitting note, faster spool and sharper throttle, this large-bore 76.2 mm setup replaces the factory front section, mid pipe and rear section for maximum impact. It is supplied with all required clamps, fittings and gaskets and it is backed by Cobra Sport’s lifetime warranty for peace of mind.

Looking for an M135i F40 exhaust upgrade, BMW 1 Series F40 performance system, M135i xDrive downpipe and system, BMW hot hatch exhaust, back box removal alternative, catless or high flow catalyst option, silenced or unsilenced mid section, valve control compatible system or a direct-fit 3 inch BMW M135i exhaust solution? This package is the enthusiast’s choice for sound, quality and flow.

Why enthusiasts choose this system

  • Full system from turbo outlet to tips for the biggest change in character and response
  • Large bore 76.2 mm pipework optimises flow and reduces restriction
  • Unsilenced rear section for a motorsport-inspired tone
  • Choose silenced or straight-through mid section to set the volume level you want
  • Available with active valve control or a fixed-open setup to suit how you drive
  • Pick catless or a high flow sports catalyst to match your build
  • All hardware included for a straightforward, bolt-on installation
  • Cobra Sport lifetime warranty

We have fitted this system in-house and customer feedback has been outstanding. Owners report a deeper note, more urgent spool and a responsive feel on the road. If you want your M135i xDrive to sound and feel like a serious performance hatch, this is the one.

Configuration guide

  • Silenced mid section (resonated) - refined when cruising, sporty under load
  • Straight-through mid section (non-resonated) - louder and more raw
  • Valve control (valved) - retains OE style valve operation so drive modes influence sound
  • Fixed sound (non-valved) - consistent, carefully tuned tone at all times
  • Sports catalyst - high flow cat for performance with reduced odour
  • Catless option (de-cat) - maximum volume and flow for track use

Tailpipe finishes

  • TP19 - 4.5 inch chrome
  • TP38 - 4 inch chrome, inverted
  • TP106-CF - 4.5 inch slash cut carbon fibre
  • TP107-CF - 4 inch slash cut carbon fibre

Compatibility

BMW 1 Series F40 2019 onward: M135i xDrive and M135ix.

Note: Where the system deletes the PPF/OPF/GPF, it is for motorsport and off-road use only. An ECU recalibration is mandatory on PPF-equipped cars to prevent an EML warning.

Back box delete systems without a rear silencer will be extremely loud.
