I am calling my self out as the pitiful owner. I have a 2008 that I purchased brand new. I have 1869 miles on it. i keep stabil in it and keep the battery charged. this year i have vowed to ride it more. i dropped it off at the shop yesterday for an oil change and to address a recalled part. when i got the bike, i put a 6over, chromed the factory wheels and put a set of shorty slip ons on the busa. my problem is, the slip ons look cool but are extremely loud, almost Harley Davidson like. i want to swap the slip ons for a full 4 2 1 system. i have eyeballing an M4 system. i recently came across Black Widow Exhausts. Any thoughts on their systems?? What power commander is recommended for the Busa. thanks for your input.
