I want to put a set of header on my 2003 1500 Quadcab Shortbed 4x4 5.9L and was wondering what to use? Longtube, mid-length, or shorties? What diameter pipes, and where can I get them for cheap....I am in college and am tight on money. I dont care if they are coated or not, as I am not going into racing with the truck, just want to free up the exhaust system. Also, do the headers have any problem fitting in the engine area or will there have to be some work to fit them in? Thanks.
