Just recently I was driving and then heard a little bang noise. All of a sudden next time I hit the acclereation it sounded louder than normal, like a rough sound (loud buzzing) I haven't really maintained the car, but its been running really good because I only drive the car 2 miles a day. I just want to know what it could be from the louder acceleration, also sometimes when I am accelerating when I park I hear a little rattling noise coming from underneath the car. I'm thinking a loose hose in the exhaust or something like that. If anyone had a similar noise or knows what it could be please let me know.

Sounds like you may have a cat converter on its way out. This could explain the rattle and the louder engine on acceleration. Have a shop check it out for you, it will effect the performance and mileage of the car

How much would a job like that cost?

With only 62k on it, you may want to find out if Toyota will cover it, they are obligated longer than th estandard warranty on emissions related items such as this. It will be very expensive otherwise
