Transform the rear of your M140i with premium tailpipe finishers that look factory fresh and fill the diffuser properly. This is the simple visual upgrade every B58 owner should make.
Crafted by Cobra Sport from high quality stainless steel, these straight-cut 88.9 mm tail trims deliver a bigger, cleaner and more purposeful look than the tired original outlets. They are designed as a direct swap for the F20 and F21 M140i with the 3.0 B58 engine, pushing onto the existing locator pins for a secure factory-style fit with no cutting and no welding.
Choose the finish that suits your build: mirror-polished stainless for a bright OEM-plus appearance or stealthy ceramic-coated black for a subtle motorsport vibe. The larger 3.5 inch outer diameter is approximately 15% bigger than stock, so the tips sit perfectly in the bumper aperture and instantly modernise the rear end. Stock pipes are notorious for corrosion over time. These premium replacements fight rust and discolouration, keeping your BMW looking sharp.
We run these on our own M140i and they are one of the highest impact visual mods per pound. Customers love the fit, the quality of the materials and the way they complete the back end of the car.
