revhard mani is hardly the best. maybe the best cast iron, but that doesn't really say much does it?
inlinepro is cast stainless, and it kind of copied off of the revhard design, but that manifold is SICK.
even better htan that is the full race manifold. 8 gauge stainless cant be beat. guarantee that it will never crack.
full race's kit is dope, but totally overkill for a street car. you have to take off a/c. i'd only get the full race kit if i was going to have a crazy built motor and a standalone.
