I Wanted To Know If Its Bad That Oil Is Leaking From The Muffler And Why Does This Happen Does Anyone Have Any Ideas About Why Or What Can I Do To Solve This Problem

What car and what mods?

ring failure?
valve guides and seals?

I'm thinking extreme valve seal issues, otherwise it would be hell to start. Bad rings would mean a lack of compression.

leaky headgasket? my sable did the same thing shorly b4 blowing the headgasket rolling over 187k run a compression test see what you find there.

no offense intended but are you sure its not just dirty water condensation from inside the muffler? water will condense in there and turn black obviously from all of the dirt.

Agreed, normally the exhaust is too hot, and oil will go up in smoke when it touches the hot exhaust system.

This is actually a drain hole for condensation in which it mixes with carbon to make it seem to be a oily substance it's H20. The drain hole is normal it keeps the muffler from prematuraly rusting out .
