Going to follow the great instructions I've found on the forum tonight and debaffle my 09 900 Custom SE because the sound is my only complaint. I hope it sounds good when I'm done and saves me hundreds on a whole new exhaust. Plus I love the looks of the flat black exhaust, just not the sound! I am going to do what I have not seen on here though and take a video of the bike running before, and after, and splice them together so people thinking about doing this can compare. I plan on going with the 8 hole strategy right off the bat! Might shoot videos at 1) stock 2) pipe cut) 3) 4 holes drilled and 4) 8 holes drilled, and post them as one video with pauses in between. That is the only thing I wish i could have seen before doing this. Any last minute advice is appreciated but I have no fear of cutting into a new bike, lol.
