Borla Touring Axle-Back Exhaust System with Polished Tips (11752) - 2005-2009 Ford Mustang GT / 2007-2009 Shelby GT500
Add a refined, deep rumble to your V8 pony car with the Borla Touring Axle-Back Exhaust System. Specifically engineered for the 2005 to 2009 Ford Mustang GT (4.6L V8) and the 2007 to 2009 Shelby GT500 (5.4L Supercharged V8), this setup is tailored for enthusiasts who want an upgraded look and sound without loud, intrusive volume. The sophisticated Touring sound profile provides a smooth, mellow exhaust note under acceleration that settles down nicely at highway cruising speeds. By optimizing airflow and increasing exhaust flow CFM compared to the restrictive factory setup, this system improves throttle response and serves as an excellent foundation for other performance enhancements.
This high-quality performance system features 2.5 inch mandrel-bent tubing crafted entirely from elite, aircraft-grade T-304 austenitic stainless steel. Superior to lower-tier T-400 series or aluminized options, premium T-304 provides absolute resistance against rust, corrosion, and structural cracking over time. Built using precision computer numerical control (CNC) manufacturing, this lightweight kit replaces only the stock over-the-axle pipes, rear mufflers, and tips for a direct, hassle-free bolt-on installation. The system routes down to a classic single split rear configuration, capped off by striking 4 inch round, rolled, angle-cut polished stainless steel tips. Engineered to eliminate high-frequency sound waves and cabin drone completely, this upgrade offers a premium driving experience backed by Borla's legendary Million-Mile Warranty.
