I have a hole in my muffler right where the pipe comes in. Will that make my car hard to accelerate?

Should not make any difference. Where a hole would cause problems is before the converter or in front of the rear O2 sensor.
If you have a problem with acceleration it could be a plugged converter or exhaust system. For that an exhaust back pressure test would show you if it is the case.
