I disagree...its not chicken or egg. The MAF and TB already flow enough to support 200+ HP...kinda why people use them for their 3.0 Hybrid projects....but the exhaust is a real limiting factor with getting the flow out of the engine. Do the exhaust 1st (if you use some common sense...and the search feature..you can do your exhaust cheaply and efficiently, and have money to spare for a nice intake) then intake.
