I have a pair also on my 02. They arent too bad at all. I am not used to the constant buzzing sound of the pipes. I rode a VTWIN before and cant get used to the inline 4 sound just yet. I would the yosh cans have just the right sound for the busa. What are you looking at paying for the cans? I will most likely have my set up for sale real soon. Yosh RS3 stainless steel bolt ons. Less then 500 miles on them excellent condition. I have a full system coming in.
