What they are saying is that the aftermarket cats aren't as efficient as 
the factory ones. Your car takes the reading from the first o2 sensor on 
the exhaust manifold, then from the second one which is post cat. This is 
where your problem lies. The cat isn't doing it's job and the sensors tell 
the tail. The aftermarket ones I've used seem to do ok and solve the 
problem. I've used both Magnaflow and Catco on imports. I got them through 
Summitracing.com Didn't seem to be any problems.
