Manifolds

Manifold components, end caps, drain plugs and exhaust elbows. Use for Ford or Chevy marine engines. GLM Marine aftermarket units are made by " Lost Foam " technology for precise specification and casting quality. They have hot dipped galvanized coating black painted for corrosion resistance.
  • GLM fully tuned design to reduce back pressure and enhance flow to add increase engine horse power.
  • Fully tuned design allows manifold to add 30 - 40% water cooling area for longer life.
  • In the 4" elbow, there are two extra exits at each side to increase water flushing to avoid engine over heating.
  • In V8 GM small block, fully tuned manifold design will guide exhaust gases directly to elbow without turbulence and back pressure. In the meantime, additional 40% water cooling area will decrease the entire body temperature significantly.
  • In V8 GM big block manifold there is an extra 30% water cooling area that will help reduce temperature in port exit area for longer gasket life. The tuned design will reduce turbulence and enhance exhaust flow for higher and maximum engine power.
