I've been looking for information on the magnum exhaust manifolds and I couldn't find what I was looking for, is the exhaust opening bigger on the magnum manifolds vs the LA manifolds? dartfreak75 said that he used manifolds for a 2001 ram 1500. I don't mind spending money for a custom down pipe for the left side as long as the benefit is there. Would midlength or shortie headers be better? Remember, I'm too am only looking to get a little extra zap. I do have a car lined up to check out but I don't want to say to much as I don't want to jinx myself. The car is pretty straight, needs a little body work in front of the wheel well looks like someone hit it.
