Description
This 3-piece stainless steel catted downpipe system is engineered for BMW S58-powered models and features integrated 400CPSI catalytic converters along with a built-in crossover pipe to balance flow between the twin turbos. Designed to reduce emissions while maintaining strong exhaust velocity, this system delivers improved performance, smoother boost response and enhanced drivability.
Crafted from premium T304 stainless steel with TIG-welded construction, the WERKE 400CPSI catted downpipes are built to withstand extreme heat and sustained high-load conditions. The integrated crossover pipe equalises pressure across both turbos, improving efficiency and ensuring consistent power delivery across the rev range.
With precise bolt-on fitment for all BMW G8X platforms, installation is seamless and compatible with factory or aftermarket exhaust systems.
