67-74 GM F Body 3in Dual Exhaust System

The 67-74 GM F Body 3in Dual Exhaust System from MAGNAFLOW PERF EXHAUST is a premium cat-back performance exhaust engineered for second-generation Chevrolet F-Body muscle cars including the Camaro and Firebird. Built for V8-powered models from 1967 through 1974, this system replaces restrictive factory exhaust with a high-flow design that improves engine breathing, reduces backpressure, and unlocks hidden horsepower. Enthusiasts restoring, maintaining, or modifying their classic GM F-Body vehicles choose this exhaust to achieve authentic performance gains without sacrificing quality or durability.

This cat-back exhaust features 3-inch diameter tubing throughout, a specification that maximizes flow efficiency for big-block and small-block V8 engines common in F-Body models of this generation. The entire system is constructed from premium stainless steel, which resists rust and corrosion far better than original steel components, ensuring longevity even in harsh climates. The natural finish provides a clean, factory-appearance aesthetic while the dual-outlet configuration delivers a balanced, aggressive tone that complements the vehicle's period-correct styling. Proper sizing and mandrel-bent bends eliminate turbulence and optimize scavenging for consistent performance across the RPM range.

Classic car builders, weekend warriors, and serious collectors benefit from this bolt-on kit, which installs directly beneath the vehicle's frame with minimal modification required for 1967-1974 F-Body platforms. The 72-pound assembly ships as a complete kit with all necessary hangers, brackets, and hardware, streamlining installation and ensuring proper support and clearance. Whether you're completing a frame-off restoration or upgrading tired original equipment, this stainless system delivers measurable improvements in throttle response, power delivery, and that unmistakable rumble that defines the classic American muscle car experience.
