Product Overview

Replace freeze damaged or corroded exhaust manifolds for GM Big Block Crusader applications.

Constant heat cycling and prolonged exposure to salt and fresh water causes exhaust system components to corrode faster than other marine engine parts. Replacement is not that uncommon. Sierra manifolds are engineered for a quick installation. Each manifold is an exact OEM match and leak tested for quality assurance. Mating surfaces are CNC machined to provide the best possible seal without additional preparation. The castings are primed and painted to stand up to the marine environment.

For 50 years Sierra has been producing parts engineered to meet or exceed the specifications of marine engine manufacturers and has gained the confidence of engine manufacturers and boat builders. Boaters and technicians can be assured a Sierra part will fit right the first time and restore function to OEM specifications. For a quick out of the box solution to damaged or corroded manifolds look no further than Sierra.
