68-72 GM A Body 2.5in Dual Exhaust System

The 68-72 GM A Body 2.5in Dual Exhaust System by MAGNAFLOW PERF EXHAUST is designed for classic muscle car enthusiasts and restoration builders who seek to enhance performance while maintaining a period-correct appearance. This dual exhaust setup significantly improves the breathing characteristics of first-generation A-body platforms, including Chevelle, Cutlass, and GTO models, by replacing restrictive single-pipe systems with a properly sized dual configuration.

Constructed with mandrel-bent 2.5-inch diameter tubing, this exhaust system ensures consistent wall thickness throughout each bend, which helps eliminate turbulence and exhaust scavenging losses commonly found in crush-bent alternatives. The dual-pipe design effectively balances exhaust pulses between cylinders, reducing backpressure while maintaining optimal scavenging velocity across the RPM range, making it suitable for both naturally aspirated engines and those with performance upgrades.

This exhaust system is ideal for 1968–1972 GM A-body vehicles equipped with either original or upgraded small-block and big-block engines. While it is designed to fit within the original frame rails, users should verify compatibility with specific suspension components and driveline modifications typical of restomod builds to ensure a proper fit.
