I have a riva free flow exhaust on my 09 FZR. I need your stock exhaust to include the plastic tubes as well as the rubber piece that attaches to the hull. In return you will get the riva free flow exhaust as well as the rubber piece that attaches to the hull that has been cut for the riva exhaust. You pay to ship me your exhaust and pay me for return shipping($30?) and it is yours. I do not post often but many tampa bay guys can vouch for me.
