Looking for opinions on the cobra f1r slip ons. Dual for my pre. They seem to be a fairly inexpensive option for the pre98. Hard to find vids or audio of them though. Anyone have experience on how loud these are(like in comparasin to D&D or other "loud" exhausts) or does anyone have any sound or video clips of them. Also, not sure how i feel about the simlistic cone styling of the f1r's. Anyone have any pics of them on a kat? Thanks
