Transform the rear of your BMW with carbon end pipes that look factory fresh and seriously premium

Give your 3 Series a sharper, motorsport-inspired finish with Cobra Sport carbon sleeve exhaust tip upgrades. These direct-fit end pipes replace the tired factory trims and deliver a larger, more purposeful 101.6 mm outlet that fills the diffuser beautifully. No cutting, no welding, just a clean push-on install that locates on the original pins for an OEM-level fit.

We have fitted these in-house and the result is spot on. Customers love the snug fit, the quality feel and the way the bigger diameter instantly modernises the rear of the car. If you want that M-style look with genuine daily-use durability, this is the upgrade.

Why this carbon exhaust tip upgrade
