2003 Lexus RX300 Q&A

2003 Lexus RX300 Question: My muffler is noisy can that be the catalytic converter?

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? -
Answer 1
yes, the cat converter assembly is about 1200-1500 installed. Roy -
Comment 1
If the only problem is a slightly noisey muffler can I just continue to drive it. There is no loss of power. -
Answer 2
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. -
Answer 3
I looked up the parts for youre car and there are three catalytic converters a front, center and rear,all three total up to about $2400.00 plus labor, -
