I had the mechanic punch out my 2 cats that come off each exhaust manifold and put in new O2 sensors. It was a last minute thing, I got the 2 uppers for free(motorcraft) and had to buy the 2 lowers (Bosch). Again I've read so much I'm exhausted to look for all the info again. will either of these things create problems for me? Thanks for any insight.
