well both are excelent intakes... you probably can't go wrong with either... i know the rpm is a great intake and so is the performer... the rpm will work best in the 1500-6500 rpm range while the performer will be best off idle to 5500... so its all going to depend on what you plan on making this do... what are your future plans for it??? is the engine totally stock??? other than the ported E7TE's??? and most of all do you have the hood clearance for the rpm intake??? it is considered a high rise dual plane intake... so those are some things to think about... hope this helps...
