I will offer some positive vibes here. Nothing is impossible if you are willing to screw it up a few times before you get it right. Best thing to do, find a scrap bike and take the exhaust off of it, maybe put on some new mufflers and call it good.
Pffffft, fenders, I prefer to get hit in the face with rocks coming off the tread… and don't leave it fenderless, that is just a stupid thing to do to a street bike.
