does anyone know how good these are suppose to be?, Im about to buy a skunk manifold and i dont know if i should buy the regualr one, or spend a little more money and get the pro. Does anyone have and usable info that may help me?

im not sure about the specific IM models. what model integra do u have? i dont kno much about LS but with a GSR ive read that top end is choked out by the manifold. i would assume the pro series has better air flow, just think with ur setup if ur gunna need that. if u dont think u r, then save ur money n dont go with the pro series.
