Cobra Sport Cat Back Performance Exhaust for BMW 1 Series F40 M135i xDrive (M135ix) 2019+ | 3in/76.2mm Stainless | Valved/Non-Valved, Resonated/Non-Res | Carbon/Chrome Tips | Lifetime Warranty

BMW F40 M135i xDrive Catback Exhaust Upgrade by Cobra Sport

Give your F40 1 Series hot hatch the soundtrack and rear-end finish it deserves. This Cobra Sport catback system uses 76.2 mm 3 inch stainless steel pipework and smooth-radius bends to replace the OPF PPF, centre section and rear box from the primary catalyst back, unlocking a deeper tone, reduced restriction and a premium look with your choice of tailpipe finish. Built for quality, tone and durability, it is backed by a lifetime warranty from Cobra Sport.

We have supplied and fitted this system for many M135i owners and the feedback has been consistently positive - great fitment, a mature yet aggressive sound when you want it and high-end tip options that complete the rear bumper perfectly.

Key reasons to choose this M135i F40 exhaust upgrade

• Free-flow catback engineered for the BMW 1 Series F40 M135i xDrive M135ix 2019 onwards
• Large-bore 76.2 mm stainless pipework replacing OPF PPF, centre and rear sections

Sound configuration

• Resonated - includes a centre silencer for a subtle, refined soundtrack on the cruise with a sporty edge under load
• Non-resonated - removes the centre silencer for a louder, more aggressive character

Valve options

• Non-valved - fixed, well-judged sports tone without valve control

Tailpipe finishes

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