Downpipe Racing BMW M3/M4 F80/F82/F83 (2014–2020) – S55 431 hp

Boost performance and give your BMW M3 or M4 a rawer sound with this Tenzo-R Racing downpipe.

Specially developed for BMW's S55 engine (431 hp), it optimizes exhaust flow and improves torque across the entire rev range.

Made from high-quality stainless steel and hand-welded with external welds, it guarantees maximum durability and performance even under tough conditions. The downpipe has an integrated cradle for the lambda sensor and is mounted directly on the car's original mounting points for easy installation.

Since the downpipe is completely empty—without a catalytic converter or muffler—it delivers an aggressive sound and a noticeable increase in performance. Please note that the engine software needs to be adjusted after installation for optimal performance.
