A clogged cat can and will affect an engines ability to rev beyond a certain rpm depending on how clogged it is. The OP mentioned only 30K on the motor, which would be low for having a clogged cat. But if those 30K miles were short trip miles before the cat could warm up, it's very possible it could be clogged at 30K.
