What I did with my MC19 was cut the exhaust from the mid-pipe throw it away and attached a muffler with a new mid pipe from a CBR250 MC22. Debaffle the pipe which made it loud but still passed WOF without any issues. You will only hear it really loud once you reach 5-6000rpm. Trying to look for a photo of it but must be in the old PC at home. Job was done by Ricky but he is in another coutry now. Cost all up $250 for a shiny second hand pipe.

if it is two loud you can try to make a baffle that you can just stuff down the pipe for wof times, chicken wire basket filled with fiberglass or something similar.

GPR have a very simple device the make a loud pipe quiet enough at WOF times. It's sort of like an ice-cream cone with holes in it. You just slip it in where the muffler bolts up to the header or joiner pipe. Very effective.
