The garage says that the sheild above the catalytic converter can collect water and has rusted and I need a new catalytic converter. The only sympton I believe is the muffler noise. The noise started several years ago and went away but is back now. Is this an expensive repair?

Question: My muffler is noisy can that be the catalytic converter?

yes, the cat converter assembly is about 1200-1500 installed.

If the only problem is a slightly noisey muffler can I just continue to drive it. There is no loss of power.

Well if it just a heat shield i would just take it to a muffler shop and let them fabricate a shield on it. I would not pay for a new cat converter. I never heard a converter rusted out since they made out of stainless steel.
If it is broken that is a different thing; then needs to be replaced since conveters can't be welded.
