64-67 GM A Body 2.5in Dual Exhaust System

The 64-67 GM A Body 2.5in Dual Exhaust System from MAGNAFLOW PERF EXHAUST is a cat-back performance upgrade engineered for classic General Motors A-body vehicles from 1964 through 1967. This dual exhaust kit transforms stock exhaust flow into a free-breathing, high-efficiency system designed for V8 engines seeking improved horsepower, torque response, and authentic dual-outlet aesthetics. Restorers and performance enthusiasts choose this system to enhance both power delivery and the visual character of vintage Chevelle, Malibu, and similar A-body platforms.

Constructed from premium stainless steel, this exhaust system features 2.5-inch diameter tubing that balances scavenging efficiency with compact underbody routing suitable for classic muscle car frames. The dual design splits exhaust flow from the engine, reducing backpressure and allowing each cylinder bank to evacuate gases independently—a hallmark of true performance exhaust geometry. Finished in natural stainless, the system resists corrosion and requires minimal maintenance, while the included 2.75-inch polished tips deliver a refined, period-correct appearance at the rear bumper. The cat-back configuration means the catalytic converter mounting point remains unchanged, preserving emissions compliance where applicable.

This system is ideal for owners restoring or upgrading 1964–1967 GM A-body V8 models, particularly those seeking bolt-on performance without extensive fabrication. Installation is straightforward for experienced builders, using existing hangers and mounting points native to these chassis. The substantial 86-pound weight reflects heavy-gauge stainless construction, ensuring longevity and durability through years of driving. Whether you're building a weekend cruiser or a show-quality restoration, this MAGNAFLOW dual exhaust delivers authentic performance and distinctive sound that honors the golden age of American muscle.
