This kit will allow your V6 Mustang to breathe better creating more horsepower torque and better throttle response. BBK's dual exhaust conversion kits include a full steel X pipe and a driver’s side tailpipe. When used with the existing passenger side exhaust pipe, it converts any V6 to a true dual system that allows the use of any GT dual axle back kit (Sold separately).

Please Note: This conversion kit designed to be used with factory or aftermarket shorty style headers and requires the use of an axle-back exhaust for a 05-10 Mustang GT and both driver side exhaust hanger brackets (NOT INCLUDED). The rear bumper cover will need to be modified to clear the driver's side exhaust tip, or you can use a GT bumper cover.
