Well there is a For Sale section at the bottom of the front page.
As for price, I guess it depends on demand. WHat I would do is perform a search on the pipes for your model, just a simple google. This will pull up current, and some past ebay auctions, and maybe some other info.
You can use this to get an idea what the exhaust might be worth.
The ride IS the adventure. The destination is just to get gas!
