Does a couple of holes in the muffler cause the engine in a toyota 4runner to stutter?

its 2.4L petrol SR5 with a manual transmission. when the car is at higher revs it doesn't seem to do it.
It also appears to reduce the power out put when I try to accelerate. but after a while it doesn't really effect the cars operation at all. I am leaning towards a muffler replacement....
so if its not the muffler, would it be the fuel filter or something else? telling me its not the muffler still leaves me with the same issue.
