Anyone ever gutted the stock mufflers? If yes is it noise tolerable?

I'm doing research on gutted mufflers. I read the guy with a tt porsche just gutted the stock mufflers with substantial powergains, 17HP, just by gutting the mufflers. He had dyno results to prove it. I'm thinking about it.

That'd save Andrew or Paul the hassle of shipping, if you really want something to experiment with. If you like, though, I'm sure I can get you sound clips of my friend's deleted-muffler allroad.
