I am doing some upgrades to my stock 330hp 7.4 I was wondering if anyone has used the aluminum glm exhaust manifolds I am looking to pick up some power and shed some weight.

you will shed some weight as they are aluminum over your cast iron but they are really no better performance wise.

Look arond for some older Kodiaks or Imco power flows. Their always around from guys upgrading to header style exhaust and will give a better perf increase than the GLM's. Don't waste your money.
