To most people, the performance gains of long tubes outweighs the simplicity of a shorty install. If you get a proper header kit you get the headers catted mid-pipes, and y-pipe. A good kit will come with the O2 sensor extension harness, so there's not a whole lot of modification required.
If you just get the header manifold, then yes, you'll need to relocate everything and it'll be a PITA.
Not to steal the thread from the OP but that is my current debate.
Whether the price tag on Long tubes are worth it, specifically the Stainless Works ones...
