Borla Axle-Back Active Exhaust System

The Borla Axle-Back Exhaust system for the 2024-2026 Ford Mustang GT (SKUs 11985, 11985BC, and 11985CFBA) is a high-performance upgrade designed to transform the stock exhaust note into a more refined and aggressive “Sound of Power.” Constructed from premium T-304 stainless steel, this system offers superior corrosion resistance compared to lower-grade alternatives. The S-Type series delivers a moderate, deep muscle car growl, utilizing ultra-smooth mandrel-bent tubing and patented multi-core technology to maximize exhaust velocity and airflow. This engineering ensures that the enhanced sound is backed by improved engine efficiency and a drone-free cabin experience.
