Dude...I'm sorry, I gotta ask you...what the hell are you doing?
You're driving around on a brand new $20K motorcycle, and you're drilling holes in the baffles to get the sound that you want? You obviously know that the 2010 model you have is equipped with a cat in the headpipe. Drilling holes in the baffles, or just installing slip-ons isn't going to do much to increase performance, cool the engine down, or let it breathe.
Do yourself a huge favor and invest in a quality stage 1 set up. That means buying a full exhaust system (Vance & Hines Pro Pipe, D&D Fatcat, Thunderheader, etc), a decent air cleaner (Arlen Ness, K & N, SE, etc), and a Fuel Management system (V&H Fuel Pack, Power Commander, etc).
You've invested in excess of $20K into this bike already, why would you ever want to do something as half assed as drilling holes in the stock pipes? Just my dos centavos.
