CP-E Ford Fusion 14- QKspl Downpipe Stock Flange Back 2.25 or 3.00 Catback Connection 304 Stainless Steel NO CAT OFF ROAD USE ONLY

The CP-E QKspl™ Ford Fusion Catted Downpipe is designed for seamless integration with the stock turbo flange of the Ford Fusion. It is constructed from premium American-made "bright annealed" 304 stainless steel with mandrel-bent tubing for optimal and less turbulent exhaust gas flow. The downpipe features three O2 bungs: two for factory O2 sensors and an additional port for easily installing a wideband sensor. An optional high-flowing catalytic converter utilizes a metallic monolithic honeycomb catalyst for maximum flow. For the off-road downpipe variant without the high-flow cat, a CP-E® Smart O2 Simulator is included to help prevent check engine lights. This product is designed for track-only use and is not California emissions compliant. It is noted to provide over 5% gains in upper RPMs.
