BBK true-dual conversion kit for 2005–2009 Mustang V6 converts the factory single exhaust into a 2.5" true dual system with an X-pipe and high-flow catalytic converters to increase sound and flow. Intended for use with shorty-style headers and an axle-back exhaust, the kit includes a drivers-side tailpipe and mandrel-bent tubing to deliver a more aggressive exhaust note and improved aesthetics, while requiring minor bumper clearance modifications.
