Restore crisp flap control and the intended soundtrack of your Remus valved system with this genuine return spring. Part Number: FD0015V. Built by Remus for their valved sports muffler on the B58-powered BMW M140i and M240i, this precision coil spring brings back smooth, reliable movement of the exhaust butterfly for consistent sound and drivability.

Why this genuine Remus spring is the smart fix

• Direct fit for the Remus valved muffler on BMW M140i and M240i B58 platforms.
• Restores proper flap operation for clear mode transitions in Comfort, Sport and Sport Plus.
