Product Description

The BBK Short Mid X-Pipe completes a long tube header install on the 2011-2014 Mustang GT or Boss 302, converting the factory H-pipe layout into a merged X-pipe for improved exhaust scavenging. Built from 3" mandrel-bent stainless steel tubing with high-flow catalytic converters, it boosts horsepower, torque, and throttle response while adding an aggressive exhaust note.

Ball-and-socket connectors simplify installation and allow adjustment for ground clearance, and rear oxygen sensor bungs sit in the factory location for a clean fit. This X-pipe is required when installing BBK long tube headers (PN 1633/16330/1856/18560) to complete the exhaust system.

Backed by BBK's 1-year factory warranty. Note: O2 wire harness extensions are needed for installation and sold separately. This part cannot be sold or shipped to California residents and is not CARB approved.
