i have put my 2000 cavi on a scanner and its says the exhaust gets up 1300 degrees at full throttle im not sure if thats good or if my cats bad could anyone tell me thanks

"Calculated converter temperature"? If so I have seen much higher on very stock vehicles.

Well a clogged convertor getting to hot there would be signs of the car running poorly.I do not know the exact temp the conv is while at normal range.As long as the car runs fine not coughing,choking engine and u can feel a consistance flow out the muffler I would not worry to much about it.I have had a clogged cat and car ran bad cat very hot,I just cut the convertor off ran straight pipe till I had a new one installed.They do get pretty warm regardless.My share

Normal temp is like 1200-1600... lol
