Supersprint BMW F8X M3 / M4 Stainless Rear Exhaust - Valved

989634KT

Upgrade the exhaust system on your BMW with the Supersprint Rear Valved Exhaust, engineered as a direct-fit replacement for the factory rear muffler. Positioned within the rearmost section of the exhaust system, this precision-built component is designed to reduce restriction and improve exhaust flow, delivering a more refined and engaging exhaust note.

Constructed from premium T304 stainless steel, this Supersprint component is designed for long-term durability, corrosion resistance, and precise fitment. Every weld and bend is engineered to maintain consistent exhaust flow and reliable sealing under all operating conditions.

Founded in 1955, Supersprint has built its reputation on engineering complete exhaust systems rather than individual components. Every Supersprint product reflects decades of motorsport research, advanced manufacturing techniques, and a commitment to maximizing performance, sound quality, and visual appeal for BMW engines.
