Running an aftermarket exhaust/ slip-on “can” or “silencer” really shouldn’t make a difference. Regardless, if you’re still running lean when up to operating temps it might be a good idea to pull the bowls on the carbs to check the floats aren’t sticking and there’s no bits or gunk in any of the ports/lines. Also, if the bike has set any lenght of time before, or after purchase, it might be helpful to purge the tank and fuel lines.
I’m glad you’ve got it rideable
P.S. The bang-and-pop is a thing some riders like and why they switch to aftermarket slip-on exhaust.
Best of luck
Cheers,
