Header-Back Exhaust Kit 67-68 Camaro/Firebird V8

The Flowmaster Header-Back Exhaust Kit for 1967–1968 Chevrolet Camaro and Pontiac Firebird V8 engines is a complete bolt-on performance exhaust solution engineered for classic F-Body muscle cars. This kit replaces the factory exhaust manifold and runs the full system back from the cylinder head, delivering improved engine breathing, weight reduction, and the authentic American Thunder tone that defines the classic muscle car experience. The stainless steel construction resists corrosion and oxidation through decades of storage and seasonal use—a critical consideration for restoration projects and collector vehicles.

Built with a 2.5-inch tailpipe diameter, this header-back system optimizes exhaust scavenging for small-block V8 performance without requiring engine modifications. The natural stainless finish provides both corrosion resistance and a period-correct appearance that complements original restorations. As a complete kit, it includes all necessary pipes, hangers, and sealing components for direct installation. The integrated design balances backpressure and flow characteristics to maintain factory-compatible engine behavior while unlocking the V8's acoustic potential and removing restrictive original components.

This exhaust system is purpose-built for first-generation Camaro and Firebird owners undertaking restorations, performance upgrades, or long-term storage preservation. Whether preparing a vehicle for cruising, shows, or seasonal use, a complete stainless steel header-back system eliminates rust concerns and ensures reliable exhaust flow. The Flowmaster American Thunder line is recognized for balancing stock-like drivability with enhanced exhaust note—appealing to builders seeking authentic improvements without radical modifications.
