Product Overview
Since mid-1964, Mustang has always been about muscle, looks, and loads of customization options. Borla's lineup for the Mustang GT and Shelby GT500 lives up to this legacy, with systems to meet a wide variety of performance goals and budgets. For soundaholic Mustang GT drivers who won't settle for anything less than unbridled performance with a pure, aggressive pony car growl, Borla offers a Cat-Back (PN140318) and Axle-Back (PN11777) system, each featuring Borla S-Type mufflers. Both are also available with Borla's more sound-absorbing Touring mufflers (PN140319) and (PN11778), for sleeper fans who prefer to be more subtle about their power upgrades. Responding to the high-output exhaust needs of the supercharged 2010 Shelby GT500, Borla engineers developed a specially-tuned Multicore Cat-Back system (PN140320) which includes an X-Pipe. Borla's patented high-velocity Multicore design distributes exhaust gases through multiple straight-through perforated cores. A race-tested innovation, Multicore technology is also utilized in Borla's elite XR-1 mufflers used by winning teams in NHRA, Baja 1000 and many other racing venues, and has been proven to actually outflow a straight pipe. System features high-quality T-304 austenitic stainless steel construction, ultra-smooth mandrel-bent 2.5" tubing, flawless welding from master craftsmen, dual 4" diameter angle-cut rolled edge 12" long bright chrome on T-304 stainless steel tips, 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.

Installed behind the rear axle, Borla ATAK axle-back exhaust systems replace the factory rear muffler(s) and exhaust pipe(s). Following the same exhaust path and secured using the original hangers and rubber isolators, Borla axle-back (rear section) performance exhausts are less restrictive than factory exhaust systems. Welded tips are standard on most systems.
ATAK (Acoustically Tuned Applied Kinetics) technology is designed for high-performance purists who prefer exhaust sound over their stereos. ATAK-equipped exhaust systems deliver the highest available dB (decibel) levels in the Borla street-legal lineup. Unlike inferior brands that lose significant sound quality at higher volumes, ATAK systems are tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output. They are calibrated on a vehicle-by-vehicle basis and their specifically-tuned internal muffler cores deliver the most desirable sound.
Many vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the rear axle; so most Borla ATAK axle-back installations are completed in less than an hour with no cutting of the factory system. Vehicles that don't have a factory service-point require cutting, so Borla includes easy-to-follow instructions and hardware to complete the installation.
Borla pioneered the use of aircraft-grade 304 stainless steel tubing, a material with a higher content of carbon and nickel that won't rust or corrode, for the automotive exhaust aftermarket … including Borla ATAK axle-back exhaust systems with the power of race-winning Borla Multicore technology.
