BMW 3 Series (G20/G21) Carbon Fibre M Performance Tips - OEM Style Larger 4" Slip-on Replacement Tailpipes

Instant rear-end upgrade for G-Series BMWs. Bigger 4 inch carbon tailpipe ends with a factory-style fit and a premium motorsport look.

Swap tired stock exhaust trims for a dramatic, high-end finish. This pair of Cobra Sport carbon fibre tailpipe finishers slides straight onto the original locator pins for a true direct fit, no cutting or welding required. At 101.6 mm outer diameter, they deliver a bold, aggressive appearance with over a 10 percent increase in size compared to the standard tips, transforming the stance without changing the exhaust system.

We’ve fitted these in-house and the results are superb: tight fitment, quality weave, and a serious visual uplift. Customers love the OEM-plus styling and the corrosion-resistant construction that won’t suffer the rusting seen on many factory chrome trims.
