Borla Axle-Back Without Active Exhaust System

The Borla Axle-Back Exhaust systems for the 2024-2026 Ford Mustang GT (specifically SKUs 11983, 11984, and their variations) are high-performance upgrades designed to transform the stock exhaust note into a more refined and aggressive “Sound of Power.” These systems are constructed from premium T-304 stainless steel, which offers superior corrosion resistance compared to lower-grade alternatives. The series is divided into the S-Type (11983) for a moderate, deep muscle car growl and the ATAK® (11984) for those seeking the loudest, most race-inspired volume. Both utilize ultra-smooth mandrel-bent tubing and patented multi-core technology to maximize exhaust velocity and airflow, ensuring that the enhanced sound is backed by improved engine efficiency and a drone-free cabin experience.
