Have you looked at the OBX header? it costs a little more then the Spyder you posted but not by much. if you don't have much money to spend on a header then that's what i would suggest.
btw, where in Maryland are you? I'm a Marylander my self
what kind are you looking for? Cause i know they have an open-mouth style grill on ebay right now for the 04-04 hatch
