Description
This fully de-catted stainless steel downpipe is engineered to suit BMW B48 engines, delivering improved exhaust flow and sharper turbo response by eliminating the restrictive factory catalytic converter.
Constructed from premium T304 stainless steel, each WERKE downpipe is TIG-welded, durability tested, and designed for optimal performance under both street and track conditions. The de-catted configuration maximises exhaust velocity, reduces backpressure, and enhances turbo spool for a more responsive and engaging driving experience.
This is a direct bolt-on upgrade with precise fitment across a wide range of BMW F-series and G-series B48-powered vehicles.
