GLM Manifolds
GLM Manifolds are Superior in the Aftermarket
Marine Parts Industry. 
Designed to Increase Performance,
Reduce Back Pressure
and Add More Horsepower to Your
Engine!
Our fully tuned design guides exhaust gases directly to riser
without turbulence and back pressure. This increases the engines
performance up to 10%. In the meantime, an additional 40% water
cooling area will decrease the entire manifold body temperature
significantly
