Cobra Sport Turbo Back Performance Exhaust for BMW M135i F40 xDrive (M135ix) 2019+ - 3in/76.2mm | Valved/Non-Valved | Resonated/Non-Res | Sports Cat/De-Cat

BMW F40 M135i xDrive Full Turbo-Outlet System by Cobra Sport

Give your BMW 1 Series hot hatch the soundtrack and flow it deserves. This Cobra Sport system runs from the turbo outlet to the tips in free-flowing 3 inch 76.2 mm pipework, replacing the factory front section, mid section and rear silencer assembly to deliver a deeper tone, sharper response and a seriously premium finish. Choose silenced or straight-through, switchable valve control or fixed sound, plus high flow catalyst or straight-through downpipe options to tailor volume, character and performance for road or track use.

We fit these in our Warwickshire workshop and the results are superb. Fitment is spot on, the sound is addictive and customers rave about the quality and the way it transforms the M135i driving experience.

Why this upgrade belongs on your M135i

• Large-bore 3 inch 76.2 mm turbo-outlet to tailpipe layout for maximum gas velocity
• Pick your tone: resonated for refined performance or non-resonated for a louder, rawer sound
• Choose valve control to retain factory drive-mode flap operation or go non-valved for a consistent note
• Front section options: high flow sports catalyst or decat downpipe for track-only applications
• Premium tip styles including chrome and carbon fibre to finish the rear perfectly
• Supplied with all required clamps, mounts and gaskets for installation
• Backed by Cobra Sport with a Lifetime Warranty for the original purchaser

Sound choices

Resonated adds a centre silencer for a smooth, mature note on the motorway with a purposeful growl on throttle. Non-resonated removes the centre silencer for a louder, more aggressive soundtrack and enhanced presence.

Valve control options

Valved systems keep the OEM flap functionality, so Comfort and Sport modes still alter the tone. Non-valved systems provide a fixed, sporty note without affecting drivability.

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 onwards including M135i, M135i xDrive and M135ix.

What you get

Complete turbo-outlet system comprising the front section, centre section and rear section with chosen tip style, plus all relevant fittings and gaskets.

Important usage note

Options that remove the GPF PPF OPF or use a decat downpipe are intended for motorsport and off-road use only. On OPF-equipped vehicles an ECU recalibration is mandatory to avoid an EML. Check local regulations before use on public roads.
