Since mid-1964, Mustang has always been about muscle, looks, and loads of customization options. BORLA®'S lineup for the 2010 Mustang GT lives up to this legacy, with systems to meet a wide variety of performance goals and budgets. For Mustang GT drivers who won't settle for anything less than unbridled performance with a pure, pony car growl, BORLA® offers a Cat-Back™ system (PN140318) and Axle-Back system (PN11777), each featuring BORLA®'S S-Type mufflers. Systems are also available with BORLA®'S mellow Touring sound, Cat-Back™ system (PN140319) and Axle-Back system (PN11778), for sleeper fans who prefer to be more subtle about their power upgrades. Cat-Back system (PN 140329) featuring our aggressive ATAK® sound is also available. With all three sound levels we offer a no drone guarantee. The exhaust exits thru single mirror polished 4" round angle-cut rolled edge 12" long bright chrome on T-304 stainless steel tips on each muffler. The system features high-quality austenitic T-304 stainless steel construction, ultra-smooth mandrel-bent 2.5" diameter tubing, flawless welding from master craftsmen, and an unrivaled Million Mile Warranty.From the dimensions and perforation patterns of the inner cores to the amount of composite filament packing, all specifications of BORLA® mufflers are tuned on a vehicle-by-vehicle basis for an optimum blend of performance and sound. Combined with distinctive motorsport styling, easy bolt-on installation and enhanced fuel economy, the world's most winning exhaust continues to lead the industry it founded over 40 years ago.
