I've got that same K&N setup on my 98 along with flowmaster and a high flow cat. I also went with the Granitelli MAF. the K&N will run you about 250-300. As far as headers go, I've found a set on ebay for $300 but I don't know how good they are. I'm seriously thinking about getting those and the Jacobs electronic ignition controller for $350. With just the K&N and the exhaust and Hypertech with the 160 degree thermo mine seems to run very well.
