Hey man, love your mod list. I have some opinion questions. I'm thinking about doing the 5" Raptor Ovals(stainless). How does the 4" look? Also, how do you like your CAI? Any noticeable power/mpg increases? Is it really noisy? I've got a buddy with an '07 4.7 with a CAI and it sounds like he's got an air hose with 4000 psi blowin through it . Thanks in advance.
