Borla ATAK Axle-Back Exhaust System with Polished Tips (11806) - 2005-2009 Ford Mustang GT / 2007-2009 Shelby GT500
Unleash the highest available decibel levels and raw muscle car sound from your V8 pony car with the Borla ATAK Axle-Back Exhaust System. Custom-engineered for the 2005 to 2009 Ford Mustang GT (4.6L V8) and the 2007 to 2009 Shelby GT500 (5.4L Supercharged V8), this high-performance setup is custom-tailored for purists who prioritize an aggressive exhaust note over their car stereo. ATAK (Acoustically-Tuned Applied Kinetics) technology is designed to maximize sound volume while maintaining crisp, race-inspired acoustic clarity. Unlike ordinary loud exhausts that suffer from harsh distortion, the ATAK system shapes and refines sound waves like a graphic equalizer, delivering an exceptionally aggressive, track-ready roar that is especially intense on supercharged Shelby platforms.
This premium performance exhaust features high-flow 2.5 inch mandrel-bent tubing crafted entirely from aircraft-grade T-304 austenitic stainless steel. Engineered to far outperform lower-tier T-400 series or aluminized steel options, this heavy-duty material offers ultimate protection against rust, corrosion, and structural cracking. Precision computer numerical control (CNC) manufacturing guarantees an exact, hassle-free bolt-on installation that utilizes standard factory hangers and replaces only your restrictive stock rear mufflers. The assembly routes down to a classic single split rear configuration, culminating in striking 4 inch round, rolled, angle-cut polished stainless steel tips. Engineered with patented straight-through, multi-core technology to eliminate interior cabin drone completely, this aggressive system is backed by Borla's world-renowned Million-Mile Warranty.
