Can someone explain to me why my bike runs 50% better after I put new replacement muffler on. It's amazing how much power I got back. Do baffles make that much difference? My old ones did not have baffles, the news ones do.

Is the power gererated from the back pressure?

Yeah, the engine is designed to work "against" a backpressure.
Sort of like the way a speaker works better if it's in an enclosure - it needs to work against that restrictive backpressure.
Take the same speaker and just suspend it in the air, with no enclosure, and it sounds real puny.
Further, the speaker's enclosure dimensions are engineered to match up with the speaker's specifications - wrong size enclosure (or none at all) provides less than optimal results.
