It's an akropovic pipe. It runs about 1000 buckeroonies!
It looks like the akropovic you can buy, but it isn't the same. That particular pipe is custom made for factory Yamaha. Unless your last name is Stewart, Chisholm, Langston, Hill, or Hepler (and now Hamblin), you can't ride with that exact pipe. Same deal with the suspension, custom works suspension straight from KYB.
