    I had my catalytic converter replaced with an after market one four months ago. Last week I had my muffler replaced, and the man that replaced it said the converter was not done very well and he welded a spot on it for me. Since then, my check engine light has been on. I have been told not to be concerned about the light being on because the computer doesn't recognize after market catalytic converters. Is this true. Should I stop worrying about it.

    My 05 Odyssey had 4 catalytic converters on it and ALL burned out. Honda charged me about $1,000.00 every single time to replace them. They said they didn't know why they went bad. I finally had a non-Honda mechanic be honest with me and tell me that I had a leak in my fuel system which was apparently not worth fixing. He told me to sell the vehicle. Wish I had known this MUCH earlier from the Honda service technicians. Apparently this is a VERY common problem with the Odysseys. Why hasn't there been a recall???!!!

    My check engine light came on and I was told it was the Catalytic Converter. We tried a gas additive and using higher grade gas. It stays off for a while after it is reset, then comes back. Now we are thinking of replacing the Converter with an after market Converter. Hoping this will solve the problem.

    Had to have Catalytic converter replaced. I shopped around after the dealership quoted me $800 to $1000 to do the job. Had replaced locally for $225. Lost a lot of faith in the dealership after this. Fixed problem. This was around 4 years ago.
