BMW M140i Tailpipe Finishers - 3.5 inch OEM-look Upgrade
Transform the rear of your BMW 1 Series hot hatch with this premium pair of Cobra Sport tailpipe finishers. Precision-made for the F20 and F21 M140i with the B58 3.0 petrol engine, these straight-cut 88.9 mm outlets deliver an OEM-plus appearance that fills the rear valance and replaces tired, rusty factory ends with a clean, high-quality look.
Choose from two sleek finishes to suit your build: mirror polished stainless for a classic motorsport vibe or stealth ceramic black for a subtle, aggressive style. At 3.5 inches, these exit trims are approximately 0.5 inch larger than stock, giving a broader, more purposeful stance without looking out of place.
