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 specifically engineered for classic General Motors A-body vehicles from 1964 through 1967. This dual exhaust kit is designed to enhance stock exhaust flow, providing a high-efficiency system tailored for V8 engines seeking improved horsepower and torque response.

Constructed from premium stainless steel, this exhaust system features 2.5-inch diameter tubing that optimizes scavenging efficiency while maintaining compact underbody routing suitable for classic muscle car frames. The dual design effectively splits exhaust flow from the engine, reducing backpressure and allowing each cylinder bank to evacuate gases independently, which is essential for true performance exhaust geometry.

This system is ideal for owners restoring or upgrading 1964–1967 GM A-body V8 models, particularly those seeking a straightforward bolt-on performance solution without extensive fabrication. The natural stainless finish resists corrosion and requires minimal maintenance, ensuring a refined appearance at the rear bumper that complements the vintage aesthetic of Chevelle, Malibu, and similar A-body platforms.
