cat converters for disco II - query

[discomummy]

Hi,  

My disco is in the garage for repairs and they are telling me that the cat converter needs replacing.  they are proposing to put new steel converters in and weld it to the existing pipes - is this a good way to go?  I have to say that the only reason the disco is with them is that they are finally repairing the damage they caused a year ago (long story) and i have to wonder if they want to make some money out of me as well.

i would like to know if i don't replace the cat converters - how much damage would it cause to the engine and how quickly do i need to replace them - i need to know if this actually needs to be done right now and i do not have a lot of faith in this garage.  

thanks in advance

sounds to me like there pulling a fast one. Provided the cats havn't collapsed inside you won't do any damage to the engine even if they've worn out, My advice is keep your money in your wallet till MOT time.
