Hi,  Like the alot of people I have had my cat stolen, I put  one on but my management system lights are on.  Help  Looking a for a new, better or original one. Where can I get?  FYI: original cat from toyota is 2600 pounds 😳😳😳 (190 Ts 2005)  I've also been told that if it not an original cat this problem can't be solved? Is this true?   Thanks Charlie  Ps I'm still sorting things out regards to the sensors. Just want to make sure I can get the right parts
