'07 Catalytic Converter

Has anyone ever changed their cat's on a 2007 Tahoe? I'm coming up on 200,000 miles and can't get the code to go away. I have changed all the O2 sensors and still nothing. If you have changed them, who did you go with? I've heard that if you don't go with OEM, you will run into problems. Any truth to that? Thanks in advanced.

Magnaflow makes a decent kit thats a good replacement. Runs about the same price as OEM. Personally, I would stick with the OEM. I think they run about $450ish
