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



naddie, 3.0L V6, Scarborough, ME, December 14, 2011, 11:30

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?

    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.
