First off ... I did drill out the baffles, and I am quite happy about the sound. Note the sound isn't LOUDER, its a deeper pitch.
1. Masonry 1/2 Drill bit ... Lowes = $11.97 (The length of the drill bit is irrelevant just needs to reach the baffles, I bought a 12 inch and was quite comfortable ... had a few extra inches to play with)
2. I felt as though I should take the exhaust off, I wasn't sure about getting the metal chips into the engine, so if anyone would like help on how to reach the exhaust let me know, I will post a guide.
3. Clamp, or ask someone to hold the entire exhaust, and proceed to drill into the very back until you feel the bit break through, you've reached as far as you need to go.
4. Enjoy the sound, its not anywhere near aftermarket ... but its a hell of a lot cheaper
