Cel came on its throwing this code...
67 Catalyst System. I just had a new cat installed, could it be an o2 sensor? or maybee a leak somewhere? My stock primary 02 sensor stripped so it couldn't go in my new header, so we found a jdm o2 sensor... could this be whats throwing the code?
thanks in advance

the secondary o2 sensor it only used to measure the efficiency of the cat. if the cat is new like you say and it's the proper one for the car even though its aftermarket there is a chance the secondary o2 is gone.......but then again there is also a chance the cat is no good either....
pick one.......or both and try change it.....

It's you cat. Any car that doesn't filter as efficiently as the stock one will throw a code since your OBD2. You can try changing your secondary O2 sensor, but I doubt it's gonna fix your problem.
