200-Cell High-Flow Catalytic Converter Downpipe

The Whoosh Motorsports catted downpipe is engineered as a direct replacement for the factory unit on the 2013+ Ford Focus ST. Constructed from 3" 304 stainless steel tubing, it incorporates a 200-cell count high-flow catalytic converter to improve exhaust flow while maintaining emissions compliance for closed-course competition use. The CNC machined v-band flange and flex section ensure a precise, OEM-like fitment, reducing turbo back pressure and enhancing turbo efficiency. Key features include robust 3" 304 stainless steel construction, a high-flow 200-cell catalytic converter, and a CNC V-band flange. This downpipe also comes with the necessary gasket and hardware for installation. Additionally, the manufacturer offers free shipping within the continental United States.
