Hi there, can I have a second confirmation that that this could work on my bike. It will probably be the only f4 with this pipe. Well maybe?

 

pretty much anything will fit a slip on if the diameter of the pipe inlet is correct. which most are..

the bigger question will be how you will mount the can.. most straps fit circular or oval.. You will need one for that tri oval shape.. I have seen F4/F4is with a TRS on it.. that mount would work.
