Hey guys i need to replace the catalytic converter. I want to know your guys experience on this. Which cat should i get the walker or the magnaflow cats any good? Let me know what you guys have used in these tbs. Thank you!
When you do replace the cat, make sure it is OBDII compliant, or you may still have the P0420, or a host of other problems.
From experience, Caddy PCMs don't like cheap cats and will not clear codes with them installed.
