Yes that hole in your exhaust could result in a loss of power.

It depends on some things. N/A car, I assume. Is the hole big? Where exactly is the hole?? Before the cat?? After the cat??
A plugged exhaust, muffler, or cat is more likely to cause your power loss, than a hole. Will the car rev up to 4-5k and hold for a few seconds in park??? Does it cut out and misfire???

If you think the cat may be plugged up, which causes too much back pressure, you could unbolt it and try driving the car to see if your power comes back.
