Product Description

In the V8 GM Big Block, GLM's fully tuned design guides exhaust gases directly to the riser without turbulance and back pressure. This increases the engine's performance. These GLM manifolds also feature an additional 30% increase in water cooling area that decreases the manifold's overall body temperature significantly. *All manifolds are powdercoated black for maximum corrosion protection* **Cast Iron manifolds come with a 3 year warranty**
