Tunable Induction makes really good intakes, the one I have is made from huge tubing and fit very nice, it also relocates the filter to the inner fender. Dont buy a cheap "cold air kit" that sucks hot underhood air though.

I have flowmasters with a catted x pipe on my car, I like the way it sounds. They never have that ****ty raspy sound to them. I've had my share of loud cars so I'm done with headaches from my exhaust. Besides i'd rather hear that blower whine then then a loud exhaust any day!
