  • Corrosion-related failure in the original exhaust manifold assembly

Installation Notes and Tips

Verify left-side fitment before installation on your 1962-1963 Chevrolet Corvette. Inspect the cylinder head sealing surface, exhaust flange, and fastener threads before assembly, and replace any damaged mating components to support a proper seal. Follow factory torque specifications and allow the exhaust system to cool fully before service.
