A/T Exhaust System - 87-93 Mustang GT

The A/T Exhaust System for 1987–1993 Mustang GT by FLOWMASTER is a professional-grade cat-back system engineered for enthusiasts who demand both performance and aggressive sound character without sacrificing street manners. This system replaces the factory restrictive exhaust, unlocking horsepower and torque while delivering the iconic rumble that defines the Fox-body Mustang experience. Whether you're building a weekend warrior or a daily-driver classic muscle car, this exhaust system addresses the primary bottleneck in stock third-generation performance platforms.

FLOWMASTER's dual-chamber muffler design uses patented scavenging technology to minimize backpressure while maintaining low-end torque delivery—critical for carbureted or early fuel-injected 5.0L engines that rely on smooth power curves. The system features mandrel-bent tubing to eliminate the flow restrictions created by crush-bent factory piping, allowing exhaust gases to exit with minimal resistance. High-quality aluminized steel construction resists corrosion better than mild steel alternatives, extending the lifespan of your investment even in harsh climates or high-humidity storage conditions.

The aggressive tone comes from FLOWMASTER's proven muffler internals, which balance acoustic character with functional exhaust scavenging rather than simple noise amplification. This exhaust system fits all 1987–1993 Mustang GT models equipped with the 5.0L V8, including both automatic and manual transmissions. Installation is straightforward, making it an ideal choice for both experienced mechanics and DIY enthusiasts.
