sometimes a clogged cat can really limit power. i had a old s10 i used to dread getting on the highway as it was insanely slow, cut it out of there and it was like i put a super charger on it.
what i usually do to check it (if you have a welder) just drill a few 1/4 inch holes in front of the cat on the exhaust pipe that you can easily re-weld. drive it after making the holes and see if that helped any
