Cheapest horsepower is an air filter IMO.
But if I had to pick a favorite it would be a muffler, the power add and the sound make it very worthwhile to me.
Now, with ALL that said, my 700xx is still BONE STOCK, but it won't in a month because I'm going to be good to myself for my birthday and probably get a programmer and a pipe.
