My car just all of a sudden doesn't have as
much power when i step on the gas and the
exhaust sounds louder when i apply the
gas. Also doesn't seem to hit over drive
when i apply the gas either.

A clogged catalytic converter could have caused the flex pipe on the exhaust to leak due to excessive back pressure. Also the added back pressure from the engine not being able to "exhale" would greatly reduce its power. Put your hand about 3 inches behind the exhaust pipe while its idling, you should feel a rapid puff puff puffing of air hitting your hand. If its just a steady weak flow or even nothing at all then there is a blockage somewhere in your pipe. It also sounds gross but a small animal may have been looking for warmth and climbed into your exhaust and passed away from carbon monoxide poisoning causing a clog.
