A GLM performance aftermarket exhaust manifold can deliver a
performance increase over a stock OEM exhaust manifold. When
designed,it can do this in two ways: by separating exhaust pulses and by
lowering backpressure. Aluminum small block weighs 50lb total!

We would like to answer a question that we keep getting asked.
Q: Are aluminum manifolds ok to use in saltwater?
A: Aluminum manifolds are OK to use in salt water! Just as the aluminum
sterndrive you have on your boat, these manifolds need zinc too. (included with manifolds)
With proper care, the aluminum manifolds will provide years of trouble free service.
