Supersprint BMW 3 Series (G20 / G21) Downpipe + Metallic Catalytic Converter Right - Left
AVAILABLE TO ORDER
Upgrade the exhaust system on your BMW G20, G21 with the Supersprint Downpipe, engineered as a direct-fit replacement for the factory downpipe. Positioned directly downstream of the turbocharger, this precision-built component is designed to reduce restriction and improve exhaust flow, reducing backpressure at the turbocharger for improved spool and power delivery.
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.
