Swapping out your restrictive factory stock manifolds for a new set of high-performance headers and matching mid-pipe is one of the best upgrades that you can do for your 2011 to 2014 Mustang GT. These powerful exhaust components give your Mustang tremendous horsepower and torque gains on top of a brutally aggressive new exhaust note that will make your Pony sound like an old-school, race-ready monster. From short tube and long tube headers to matching X-pipes and H-pipes, we only carry the top industry brands like JBA Exhaust, Magnaflow, Kooks Custom Headers, Borla and BBK Performance. These headers and mid-pipes give your Mustang GT greatly improved exhaust outflow, especially when paired with the required custom tuning. After you have a set of headers and a mid-pipe, check out our 8.8 Ford Rear End Gears, or our 5.0L Mustang Axle-Back Exhaust Systems.
