This BBK Performance Dual Exhaust Conversion Kit is designed for a 2005-09 Mustang 4.0L V6.
Now owners of the 2005 - 2009 Ford Mustang V6 4.0L can easily bolt on a true dual exhaust from the manifolds back. This kit includes a full 2.5" mandrel bent aluminized steel X pipe and a driver’s side tail pipe. 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 (not included).
