I knocked out the screen at first too. It wasn't quite loud enough so i went ahead and drilled the four holes. I'm happy with the volume of my exhaust now, so i won't be punching any more holes or going with the complete debaffle process.
You'll still have to remove the backplate to get to where you drill the holes and cut off the end of the small pipe, you know.
I haven't noticed any significant power change or mileage difference.
