Give your BMW F40 rear end the look it deserves with these carbon fibre tailpipe finishers from Cobra Sport. Designed for the 2.0 B48-powered M135i xDrive, these factory-inspired end pipes deliver a premium OE-plus aesthetic with a true motorsport vibe.
Crafted with a carbon fibre outer and premium internals, these replacement rear outlets upgrade the visual impact of the standard backbox without the need for cutting or coding. Each tip measures 4.5 inches 114.3 mm, which is 0.45 inch 11.6 mm larger than stock, equating to a substantial 15 percent increase in overall diameter. The result is a bolder, wider stance that complements the diffuser and makes the rear of the car look far more aggressive.
These slip fit exhaust finishers install directly onto the OE locator pins, maintaining a clean, secure, rattle free fit. They are a direct replacement for BMW part 18309488764, retaining the original alignment and symmetry. The superior materials help combat the corrosion and tarnishing issues commonly seen on the factory tips, keeping your M135i looking fresh for the long term.
