What are the major differences. My real question is about the exhaust manifold. I want to either get an exhaust manifold with a high flow cat or just delete the cat all together. I haven't done much research about the duratec 2.5 but I remember reading that the engines are almost identical. If i were to shop around for an exhaust manifold for the duratec would that fit the L5-VE.
I have found online that msds Inc. make a manifold.

Lastly (dumb question) should I be looking up anow exhaust header or exhaust manifold. Probably should have had this question first.
