I'm in the process of de-goating my VN, but I've run into a roadblock. The left muffler has rust welded itself onto the GB, and won't come off no matter what. I've tried percussive maintenance, PB blaster, hammer and chisel, using a screw press, and thwacking it off of random objects in my garage.
My solution is to just run some flexible exhaust tubing from Autozone to cheap $50 emgo mufflers and ditch the stock ones. Will this require a rejet? I haven't done an ear shave yet, but if this would require a rejet then I might as well.

Thanks!

No problem, Nothing wrong with asking questions. But 95% of them have probably been answered already and that’s because it’s an older bike. Between Google search or the search directly on this site you have a good shot at finding mostly everything if you don’t feel like waiting on a response.
In google you basically can type “vn750” with anything after it and it’ll direct you to this site

Historically, a change to open exhaust has usually required a re-jet. Always best just to read the spark plugs after the mods and see what it needs. Some engines will do ok with just a carb adjustment, it depends how much flow is increased. Spark plug color tells the story.

Earshaved mine with stock pipes, and it's fine on the stock jetting with no adjustment.

Sounds like the goat belly is off the bike? Muffler shop can heat it with a torch and take it apart, maybe a five minute job. Flex pipe is ok in a pinch, but I've found it rusts quickly and breaks easily, the corrugation between wraps is paper thin. The shorter piece of flex, the better.
