I don't think you can wrong with just about any setup for the 03/04. There was a syno shootout in a 5.0 mag a while back, most made the same power. seems the best of the bunch was good for 25rwhp.

I bought a densecharger setup...oops...not much more than something you could piece together in the plumbing section of your local hardware store. I like the looks of the steeda setup myself. I've been contemplating getting it for my car.

90 degree bends have been responsible for poor driveability at times. I haven't had any problems with my current setup, but others have. A lot of times problems can be corrected by clocking the MAF until the issue clears up.

I'd be most inclined to go with a straight shot setup that includes a shield to draw the air from the opening in the fender. I installed an unshielded FIPK on my car and lost 2 tenths at the track due to underhood heat. Everything about the straight shot style is better IMO, right down to filter cleaning time.
