Product Details

The Borla 11799 ATAK (Acoustically Tuned Applied Kinetics) Axle-Back Exhaust System delivers maximum sound and performance for the 2011-2012 Ford Mustang Shelby GT500. This aggressive exhaust system is engineered specifically for the supercharged 5.4L V8, providing the loudest and most aggressive sound level in Borla's exhaust lineup.

Key Features:

  • ATAK technology delivers maximum aggressive exhaust note without drone
  • T-304 stainless steel construction for superior durability and corrosion resistance
  • Precision computer-controlled CNC mandrel bending for optimal flow
  • Ultra-smooth welded construction ensures strength and appearance
  • Bolt-on installation for direct OEM replacement
  • Releases additional horsepower and torque from the supercharged V8
  • Backed by Borla's Million-Mile Warranty

This axle-back system replaces the rear section from the axle back, making it an economical performance upgrade that dramatically transforms exhaust sound while maintaining excellent build quality. Borla's patented straight-through design minimizes backpressure and maximizes performance gains. Made in the USA with premium T-304 stainless steel that will never rust or deteriorate.

Best prices on the internet. Fast free shipping. Can’t get any better than that.

My order came fast with no problems. Works great in my Ram Truck. Will buy again from Autoplicity without hesitation.

I prefer the old school method of only replacing the wiper blades instead of the entire wiper arm & autoplicity has wiper blades in stock. I received them in less than a week.
