Product Details

The Borla 11798 S-Type Axle-Back Exhaust System delivers an aggressive yet refined exhaust note that enhances performance without drone. Engineered specifically for the 2011-2012 Ford Mustang Shelby GT500 5.4L supercharged V8, this system features Borla's patented straight-through design for maximum flow and power gains.

Key Features:

  • 2.75-inch mandrel-bent tubing for optimal exhaust flow and performance
  • Split rear exit design with dual 4.5-inch round tips featuring single rolled angle-cut finish
  • S-Type mufflers provide moderate to aggressive sound level - louder than Touring, quieter than ATAK
  • Constructed from premium T-304 stainless steel for superior corrosion resistance
  • Precision computer-controlled manufacturing ensures perfect fit
  • Complete bolt-on installation with all necessary hardware included
  • Backed by Borla's Million-Mile Warranty

This axle-back system replaces everything behind the factory mid-pipes, making installation straightforward for enthusiasts. Borla's S-Type series is engineered for drivers who want a more aggressive sound than stock while maintaining daily drivability. Each system is made in the USA using aircraft-quality austenitic stainless steel that will never rust.

Item just as descibed, great price and fast shipping. This has been my first order and actually first time searching for an auto part on this site and all went as expected. Glad I saw reference to it a car forum.
