Product Description

The Borla 11806 ATAK Axle-Back Exhaust System is a performance exhaust upgrade designed specifically for 2005-2009 Ford Mustang GT and Shelby GT500 models. Built from premium T-304 stainless steel with mandrel-bent tubing, this system delivers both strength and enhanced exhaust flow compared to the factory system. Utilizing Borla's ATAK® Acoustically-Tuned Applied Kinetics technology, it produces one of the most aggressive street-legal exhaust tones in the lineup while minimizing unpleasant cabin drone.

This direct bolt-on axle-back system replaces the rear muffler section of your Mustang's stock exhaust using existing hangers and mounting points, making installation straightforward with no major modifications required. Dual polished 4" round tips and the split rear exit design not only improve sound but also give the rear end a distinctive, aggressive look. Backed by Borla's Million-Mile Limited Warranty, the 11806 system is ideal for enthusiasts seeking maximum sound and performance from their classic Mustang exhaust setup.
