rusted exhuast

So on my 91 corolla has gotten louder. I did some searching and found that the exhuast, where it connects with the exhuast manifold which is held on by two peg bolts has rusted. There is an inch or two wide hole. Thats what has made the car sound louder and like its farting. The car feels like it hasn't got the power it had before. It could be cause as it farts it just feels more sluggish than it already is. Does the exhuast need a certain compression amount like the engine on the inside needs to make the engine run at its best? I plan on getting a new exhuast put on. Be nice if I could weld.

Be nice if I could weld.

Welding skills are great to have but you still can't weld rust..:shakehead

I see a new exhaust in your future.

Its probably best anyways since the car hasn't had a muffler on it since it rusted out about 5 years ago. Doesn't sound any different without or with the muffler. How sad. I was an exhuast that will give the car a slightly nicer sound. Just not something that sounds like a pissed off hornet.
