2011-14 Mustang GT500 ARH Header 1-7/8in x 3in, 3in H-pipe No Cats.
Arguably the most amazing hot rod to ever exit a Ford factory, the
Shelby GT500 is here. With a mountain of horsepower just waiting to be
unleashed, American Racing Headers' bolt in long tube header systems
can increase power and torque by as much as 40RWHP and 40RWTQ
All ARH systems are hand-made from 304 stainless steel and are 100%
certified made in the USA. System can be configured to meet the
requirement of your specific application and includes long tube headers
(Available with 1-3/4” and 1-7/8”) and your choice of X-pipe or H-pipe.
Make your system a full exhaust system by including Pure Thunder
mufflers and polished steel tips or combine your stock manifolds
with axle back or catback systems to keep your stock manifold
but still provide increased horsepower.
