Default Curious what would happen if I drilled a bunch of holes in the muffler

Your muffler would have holes in it and it would be noisy. And blow exhaust every which way.

Swiss cheese mufflers don't work great I'm sure.
If you are wondering about easy performance gains without installing a header, just add a header.

Give it a go.

Preferably, drill them all around the current exit hole; just some satellite holes around it.

If you're feeling adventurous after that, consider slicing the muffler open around the seam--I would love to see the inner chamber(s) and baffles.

I tried it once. I kept hearing metal shaving rattling inside that I couldn't get out. I just didn't want to put it on and have them fall down an open exhaust valve.
