NINTE Carbon Fiber & Stainless Steel Exhaust Tips — BMW M Performance Universal (2pk)

The dimensions are worth knowing before you order: 63mm inlet, 93mm outlet, 178mm total length. That 30mm expansion in diameter is enough to visually widen the rear bumper presentation without requiring any bumper modification on properly fitment-checked applications. Both pieces in the set are matched, making them a natural choice for dual exhaust outlets or symmetrical cutouts in aftermarket diffusers.

Material quality is where NINTE earns its keep here. The stainless steel core resists corrosion and handles repeated heat cycling without warping or discoloring, while the carbon fiber cap maintains its gloss finish under normal driving conditions. These are not chrome-painted plastic — the carbon weave is real and visible up close.

Fitment is universal across BMW M Performance vehicles running a 63mm exhaust pipe, but that universality puts the measurement burden on you. Confirm your pipe diameter and check rear bumper or diffuser clearance before purchasing, as the wider outlet may require minor adjustments. No installation instructions are included, and professional installation — either welded or clamped — is strongly recommended for a clean, rattle-free result.
