Description
These 3″ mandrel-bent stainless steel downpipes are engineered for the BMW S58 engine, delivering maximum exhaust flow and improved turbo efficiency thanks to their fully de-catted design.
Crafted from premium T304 stainless steel with TIG-welded construction, WERKE downpipes are built to handle the high temperatures and pressures associated with tuned and track-driven S58 platforms. The smooth mandrel bends ensure optimal exhaust velocity, reduced backpressure, and sharper turbo response under demanding conditions.
