I just rescently bought a 99 F4 for a track day bike. It has an aftermarket system with a Two Brothers CF can. The problem is that the header and the mid-pipe are not made by Two Brothers. The Headers appear to be stainless. The system goes from 4 to 2 at which point it meets the mid-pipe. The mid-pipe goes from 2 to 1. Then there is an elbow and the can. the syestem is crushed from the mid-pipe back to the can. I would like to be able to replace these parts, but I do not know who makes the system. Does anyone have any ideas? Thanks
