It has roughly 169k miles. We took it in to investigate a rattle. Mech says it’s a piece of ceramic that’s come loose in one of the car’s 4(!) catalytic converters, and one needs replacing. A brand-name part is $950, but the after-market one is $450. Labor is $190. We’re located in Houston, TX. I’m thinking of going with the $450 because I’m not sure I see $500 worth of extra value in the brand-name. Agree or disagree?
Next question. Mech says that while he’s in there, I may as well go ahead and replace BOTH O2 sensors on that cat converter. He says it’ll eventually need to happen anyway, and if I do it now, there won’t be any additional labor (since he’s already opened it all up). Each of these O2 sensors is around $80. Should I do it now?
Last question: the inspection isn’t due until November. The car is currently running fine. If I put this off until November, will the problem somehow get worse and end up costing me more?
Thanks so much you guys.
