Has anyone tried a YZ pipe on their 05WR450? I found the YZ stock pipe at Bike Bandit for $202 part # 2520840-001. Does this sound right? It is not clear from the parts break-down if this is the whole pipe. If not, the cap is $70 and the outlet is another $42. I had a White Bros back-order so long it was just cancelled. If anyone has this pipe then what can you say about the difference over the stock pipe?
