I found this video which compare all exhausts for CBR250RR Very helpful if you are thinking which exhausts to upgrade and find the best sound you like. You can click on the video for all exhausts timestamps & links Which exhaust you liked the most?
Interesting idea. But I think it's worth to point out the bike being tested sounds like the new CBR250RR MC51, and not the old MC22. Unfortunately, we don't have that many options for the good old MC22.
