That's what I did and it sounds great I drilled about 5 10mm holes.If you want to get a deeper tone when you get on the gas and do it without any cost you can drill some holes in the baffle. It is positioned in the middle of the can at its lower side. You can access it with a long drill from the side of the headers. You take the can off the bike to do that, fairly easy. Four to five 6 mm holes make it sound like the 1000 Euro Akrapovic!
