Convert the single exhaust on your 2005-2009 Mustang V6 into a true dual set up with this BBK dual exhaust conversion kit. Combining a GT axle back and the included BBK Performance off road x-pipe will dramatically increase the sound of your Mustang to a roar that will be sure to turn heads. This conversion kit designed to be used with factory or aftermarket shorty style headers and requires the use of an axle back exhaust for 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. BBK V6 Mustang dual exhaust conversion kits include a full 2.5" mandrel bent aluminized steel X pipe and a drivers side tail pipe.
Since 1988 the BBK Performance brand has been synonymous with bolt on performance for modern muscle cars and trucks since its beginning in 1988. In fact it was our founders Brian & Ken Murphy that designed and developed the first aftermarket air intake systems & performance throttle bodies for the then newly fuel injected 5.0L Mustang and TPI Camaro models. Back then nobody even knew what an air intake or throttle body was because people were just learning about these modern day fuel injected pony cars Detroit began producing. Fast forward to today and many enthusiasts have only grown up on computer controlled fuel injection with a vocabulary full of upgrade items such as throttle body, air intake & mass air meter and have never driven a carbureted equipped vehicle. It?s this early experience and years of research & development, along with millions of dedicated enthusiasts that have allowed the BBK brand to grow into the largest source of modern day performance products for today?s cars & trucks. Starting from a 1200 ft building in Southern California, our BBK facilities have grown as fast as our product lines with nearly 200,000ft of state of the art design, manufacturing & distribution facilities located in California & Florida. Our R&D centers feature a total of three dyno cells and a team of highly skilled craftsman that also happen to be enthusiasts who really enjoy bringing the best performance products to market. Our manufacturing campus includes a top notch CNC machine division along with a state of the art exhaust division using a combination of skilled hand craftsmanship with a blend of CNC bending & robotic welding for maximum quality in every BBK product. Our moto is ?American Designed & Built? and it?s something the entire BBK team is proud of and will never change. If you are the owner of a modern day Dodge, Ford or GM vehicle and you are looking to upgrade your performance while maintaining OEM quality & drivability, you have come to the right place.
