Why in the world is custom exhaust so expensive for the xs 650 on ebay? there sure doesn't look like alot of work to it, but guys are selling simple exhaust designs for over $200 bucks, I mine as well go out and buy a welder and start making my own. Anyone know of a good resource for making a set of pipes that are not overpriced. I know gordonscott on here does good work, but I would like to stay under $100 bucks. Thanks fellas.
