Borla Over-Axle Mid-Pipes (60521) - 2011-2014 Ford Mustang GT 5.0L & Shelby GT500 5.4L / 5.8L V8
Eliminate the final restriction point in your S197's exhaust network with the Borla Over-Axle Mid-Pipes. Custom-engineered for the 2011 to 2014 Ford Mustang GT 5.0L and Shelby GT500 models, these premium 2.75 inch diameter connecting pipes clear the path for maximum exhaust flow. This kit is highly recommended for drivers looking to bridge the gap between a Borla aftermarket X-Pipe and a Borla Axle-Back system to form a complete, high-volume Cat-Back layout. By replacing the necked-down factory over-axle piping, this kit increases overall exhaust gas velocity, uncovers hidden horsepower, and deepens the signature Borla muscle car growl under acceleration while keeping interior cabin drone at bay.
Built to endure the harshest street and track environments, these over-axle pipes are constructed entirely from heavy-duty, aircraft-grade T-304 austenitic stainless steel. Highly superior to standard aftermarket T-400 series or basic aluminized alloys, premium T-304 construction provides ultimate life-long resistance against rust, moisture corrosion, and structural cracking under heavy thermal loads. Precision computer numerical control (CNC) mandrel bends ensure a completely uniform pipe diameter over the rear axle, eliminating internal bottlenecks to guarantee an ultra-smooth, restriction-free path. Designed for an exact fit, this mid-pipe kit utilizes original factory hanger and mounting locations for a clean installation. It is proudly backed by Borla's world-renowned Million-Mile Warranty.
