67-69 Camaro/Chevelle Bb

The 67-69 Camaro/Chevelle BB headers are purpose-built exhaust manifolds engineered for first-generation muscle car enthusiasts looking to maximize engine breathing and horsepower. These headers are specifically designed for big-block Chevrolet engines in 1967–1969 Camaros and Chevelles, addressing the factory manifold's restrictive design that limits performance potential. Whether you're restoring a classic or building a restomod, upgrading from cast iron factory pieces to quality headers is one of the highest-return modifications for naturally aspirated big-block platforms.

These headers feature tubular steel construction designed to reduce back pressure and improve exhaust scavenging across the RPM range. The stepped tube diameter design matches the flow characteristics of large-displacement big-block engines, allowing exhaust gases to exit more efficiently than factory cast manifolds while minimizing turbulence and heat retention at the engine bay. The tubing geometry is optimized for the engine bay layout of second-generation A-body platforms, ensuring proper fitment without interfering with steering components, brake lines, or other chassis systems. Weighing 38.3 lbs, they represent a material reduction in unsprung weight while delivering measurable gains in volumetric efficiency and throttle response.

Restoration shops and performance builders favor these headers for their bolt-on compatibility with original mounting points and proven dyno results on big-block builds. Installation requires disconnect of the factory exhaust manifolds and connection to your existing exhaust piping or new performance exhaust system. These are particularly effective when paired with carburetor tuning, intake manifold upgrades, or forced induction projects where scavenging efficiency directly impacts power output. Proper header selection ensures your big-block investment delivers the performance and sound characteristic of a genuine muscle car platform.
