I bought my voodoo style tips off ebay for 50 bucks. The fitment is fair. If you have done the Buell Peg mod you will need to shave some of the peg to make them fit without rubbing the exhaust. If you have factory pegs you will be fine. The ones of Ebay came with baffles. I had to take the baffles out cause it sounded like ass. The exhaust is loud as hell. Not backfire,sputtering,noticable power increase or decrease.
