It's likely Platinum or something. That's what most of the Automotive Cats are made of in some amount.
The pictures I have seen when "Drilled" out through the pipe can only have two holes about 3/4" in diameter. While that chunk is probably about 5" x 2-3" that is not a noticeable improvement.
It's worth the effort to cut the pipe gut it and weld it back up. If you don't have access to a welder I would bet you could get a muffler shop to weld it up for 20.00 or so. (Over someones lunch or something) (Get the better welder at the shop if you can! LOL)
I have a pipe coming for my bike from a guy on here. I am buying a stock pipe, and gutting it. Then I'll likely gut mine if I like the way it performs and sell it to someone on here, I imagine I'll need to MAP the bike then, I don't know.
