Give your BMW 340i a clean OEM-plus rear end with our larger 88.9 mm tailpipe finishers. Subtle, factory-correct styling with a bigger, sportier presence that looks right at home on the B58-powered F30 and F31.
Crafted by Cobra Sport from premium stainless steel and available in a stealthy ceramic black option, these straight-cut end trims replace the tired stock outlets with a wider 3.5 inch upgrade. The increase of 12.7 mm in diameter equates to roughly 15 percent more visual impact without looking over the top. Supplied as a matched pair for a balanced, symmetrical look.
Installation is simple. These slide onto the original locator pins for a direct fit on BMW 3 Series 340i models with the B58 engine. No cutting, no drilling, no welding. Designed as a like-for-like swap for BMW reference 18307610633.
