hey i'm back...okay now for this
actually chris you've got it backwards. cold air increases low end while short ram increases high end due to the difference in resonance in the intake piping. as leets said also hp is not cumulative. if a intake dynos at a 5hp increase over stock, and a cat back dynos 3hp over stock. putting them together is not going to necessarily dictate an 8hp increase. you have changed all the factors that go into making power. cutting corners on cost will cut you back in hp development. but unless you are building a all motor monster, the 5hp that is lost is not noticeable.
