The DTC or code will tell you if your cat is bad, thats what rear o2 sensor tells pcm.Determine what code you have.

Uhmm When my cat on my V6 camaro went bad, the computer limited my engine. It seemed like 5 of the 6 cylinders had shut down, i had NO power. and the exhaust(had been loud) was now, nothing more than a slight wisper.

It could be ur cat, do you have an SES light?

What year is your car?

Early production 2001 cars have a problem with bad cats, especially the driver's side.

My 2001 Z28 and 2001 WS6 were both built October 2001 and both had to have the cats replaced. (under warranty, of course)
