BBK R&D department developed these 2015-2017 S550 Mustang 5.0 Long Tube Exhaust headers with one thing in mind. Getting even more horsepower and torque out of the all new 5.0 liter Coyote Mustang that is already putting out nearly twice the horsepower of its 5.0 predecessors!
These BBK long tube header design are constructed with 1-3/4" CNC Mandrel-Bent tubing and solid 3/" laser cut exhaust flanges. Initial testing is showing gains of around 30 plus horsepower with the high flow catted X and X pipe and BBK will have an off road H version available for even more horsepower gains.
