Take a first look at the all new 2011, 2012, 2013 & 2014 Ford Mustang GT & Boss 302 5.0 BBK 1-3/4” direct fit tuned length headers and replacement High Flow Street legal after cat 2-3/4” X pipe. (available separately) . BBK R&D department developed these headers with one thing in mind – Getting even more horsepower and torque out of the all new 2011-14 5.0 liter Mustang that is already putting out nearly twice the horsepower of its 5.0 predecessor! This all new rugged BBK header design is constructed with 1-3/4” CNC Mandrel-Bent tubing and solid 3/8” laser cut exhaust flanges. Initial testing is showing gains of around 14 horsepower with the high flow after cat X pipe – and BBK will have an off road cat eliminator system out shortly for even more horsepower gains. All Headers include a set of new gaskets, required hardware and detailed installation instructions for installation.
