Can't be that much more... all you have to do is keep it one pipe and use the same bends as the stock exhaust left or right... either way. Plus they get to save on double the amount of piping that they would save and roughly ask the same price for a performance exhaust... essentially doubling their money since they can almost make two exhausts for the same price as a dual pipe exhaust... I dunno just askin.
