I have a91 max. i just bought her. She has a very bad exhaust leak, getting louder by the day!

I am not sure where the leak is coming from. How do I figure it out, what should my next move be? Oh yeah, it is definately not from the rear, the leak is next to the manifold! I was told that it could be the gasket, a hole in the system, and other bad things that i refuse to repeat! Can someone help me? Please
