After going up a large hill at about half throttle, then hitting the throttle pretty hard as some have suggested to properly seat piston rings during break-in, the engine pulled SIGNIFICANTLY harder on the level terrain afterward and the exhaust noise gained a much louder "pop" rather than a quiet hum. Is this the sound of compression increasing or some kind of muffler break? The gasket checks out OK and the oil dripping out the bottom of the muffler has suddenly stopped. thoughts?
 
You just about have to open exhaust pipe to see what broke.
The inside is a pipe crimped in center with hole in it. This is placed in plates.These restrictive plates bounse sound waves about inside the cylinder shaped canister that holds it all.
If yours has a small nut at the end it can be removed and inspected.
When what ever gave way inside it made so flow is better less pressure,more power.
If you take it off and shake it a rattle sound may be heard..
If that is what it is not much to worry about.
You may want to search exhaust or muffler or click on a site at bottom of page for better and more info.
Enjoy it.
If it is running it can't be broke that bad.
Good luck.
