Gibson designed their Axle-Back Exhaust System for one thing: to provide the sound, performance, and appearance that your 2011-2012 GT500 or 2011-2014 GT Mustang deserves. A system 2-1/2” Stainless Steel piping opens up the pathways for the exhaust to travel, reducing back pressure on the engine, while 4” polished exhaust tips create an aggressive tone. Gibson’s Axle-Back design relieves pressure from the engine, increasing gas flow, as well as improving acceleration and horsepower.
