The only negative about the holesaw mod is the mufflers may sound hollow to you after doing it. That can be eliminated by blocking the crossover tube between the mufflers with a small round disc. That will eliminate that hollow sound you hear (more of a thumping sound now)Then open the air jets to compensate for the opened mufflers.
If it's too loud for you (not too many claim it is) you can always do the "washer" mod in the end of each mufflers to control the volume.
I only wish I could make a video to show the difference in sound between the crossover mod vs without it, and the washer mod, opened and closed.
