Upgrade the rear of your BMW 4 Series 440i with premium OEM-look tailpipe trims that deliver a true M Performance aesthetic, a larger outlet size and long-lasting durability.
Designed for the F32 Coupe and F33 Convertible fitted with the 3.0 B58 engine, these 3.5 inch 88.9 mm round exhaust finishers are a simple slide-on swap that transforms tired factory outlets with a clean, motorsport-inspired look. Expect a noticeable visual boost thanks to the increased outside diameter around 15 percent larger than standard while retaining a factory-style fit and alignment.
Choose from two finishes to suit your build:
- Polished stainless for a bright, mirror-like shine
- Stealth ceramic black for a subtle, aggressive appearance
We have installed these tips on customer cars at MJ Modifications in Warwickshire and the feedback has been outstanding. Owners love the quality, the fit and the way the larger outlet fills the diffuser opening. The stainless construction and premium coating options resist corrosion and pitting, addressing the common problem of stock tailpipes discolouring over time.
