Good Deal?

I would do a little research. As far as price, The exhaust system goes for about $400 and the jet kit for $120 retail so even the starting bid is not that big a bargin. If you are serious about buying it wait until the last 30 seconds or so of the auction to place you bid. Place a bid as high as you are will to go and the automatic bidding feature will up your bid by the minimum amount.

It varies a bunch. The most expensive, Akrapovic run around $1000. Mid priced like Yoshimura $600-700. Inexpensive like Hindle (supposed to be pretty good for Kawasaki because he is an ex-Kawasaki racer) $450-$550 all depending on the type of can. Fancy can=more money.
