I picked up a 98 1200 and the exhaust pipe is rusted in the mid section. I then purchased a used 99 stock head pipe and mid section from Ebay. My bike has a Hole shot muffler that clamps on and the stock one I received has a 3 bolt flange?? Was the slip on or 3 bolt stock on my 98? Where can I get a replacement mid pipe for a slip on muffler? Thanks
