My '66 Bonneville really needs a complete exhaust system. They seem to be available from a number of sources at a fairly wide range of prices. What I'm fuzzy on what is the difference? Are there only a couple of manufacturers turning them out or are there numerous companies producing them? I just want it to look original, work well, sound good (have a voice, but not too loud) and hopefully not cost too much. I've seen a couple on eBay that looked pretty and the prices seemed reasonable. What sorts of experiances have folks been having with replacement exhaust systems on these bikes?
