Those damn Magnaflows suck, the sound is low and annoying when cruiseing, pluss the automatic trans shifting around and the throttle makes it sound like ass at that low of a tone. You end up with that annoying brrrr...!BRRRR!..brrr type sound. It sounds good in select shift tho but that will guzzle gas on up fast.
As for the CAI try a different filter I got a blitz filter and that is sick! Its got a heat shield around the filter and adds some shine under the hood when its polished well. Pluss, I dont know about the area you live in but a guy at a customes shop around here can make them with better design for around 100 bucks if its not a big pain in the ass, I cant see this beeing tuff to make at all as I seen some tubes look like a Rat maze.
One thing is that I had to get a new addapter made by a friend that was a bit longer, I had trouble fitting every filter I went with except the one it came with. IMO that one sucks.
