Matching the stock turbo, our Focus RS Catted Downpipe includes a laser cut stainless steel flange for easy installation and stock compatibility. Adding to this, our downpipe is made from premium American made “bright annealed” 304 stainless steel. Similarly it is mandrel bent throughout for less turbulent exhaust flow. We have included three O2 bungs to accommodate the two stock O2 sensors, and to give the ability to easily add a wideband sensor. The cat features a metallic monolithic honeycomb catalyst designed for maximum flow and surface area.
