RAFIQ609

Hello...ive read all the posts on catalytic converters and 2 mechanics narrowed it down to needing a new rear converter after changing the 02 sensor from a code p0420. I just want to know the name and part number of the rear converter. Mechanic said its by the firewall. And what is the best converter to buy price wise oem and aftermarket? Thanx alot!!!!

I think Catalytic converters might be warrantied by the manufacturer for up to 15 years? Are you talking to Lexus mechanics?
