Catalytic converter question
. It was a very tough decision but the wife "allowed" me to buy a diesel and I couldn't pass up the opportunity.Anyway I sold the Bronco to a good friend who I know will take good care of it and he failed the emission test and is told to replace an o2 sensor and 1 of the 2 CATs. I was wondering if he could put on a hi-flow instead, would he need to take both off for a hi-flow or does he just replace the bad one that they say needs to go with the hi-flow, or should he just go OEM? Here are the numbers they gave him for the CAT 097-1200-8 and 15742. I'm not sure which CAT it is but I hope those help.
Thanks for your help.

Also, the high flow cats don't cost all that much.
