Borla 2.75" Over Axle Mid-Pipes (60521) - 2011-2014 Mustang GT & 2011-2014 Shelby GT500
The Borla 2.75" Over Axle Mid-Pipes are designed to complete a full high-flow Cat-Back system on 2011-2014 Mustang GT and 2011-2014 Shelby GT500 models. Intended for use with Borla Axle-Back systems and the Borla 2.75" X-Pipe, these Mid-Pipes replace the restrictive factory over-axle section with smooth, mandrel-bent T-304 stainless steel tubing for maximum exhaust flow and performance.
These 2.75" pipes are engineered to handle the airflow demands of both naturally aspirated 5.0L Coyote engines and the supercharged 5.4L/5.8L GT500 powerplants. The increased diameter and optimized routing improve throttle response, enhance exhaust tone, and support higher horsepower applications. Precision CNC manufacturing ensures a perfect fit on all coupe models from 2011-2014.
Constructed from premium T-304 austenitic stainless steel, these Mid-Pipes offer superior durability and corrosion resistance compared to lower-grade T-400 series materials. When paired with Borla's X-Pipe and Axle-Back, they create a complete Cat-Back system backed by Borla's industry-leading Million-Mile Warranty.
