You have to consider that modifying the exhaust will directly affect the mapping on the bike! By opening it up, it will flow more out the exhaust, causing a mixture change in the computer. Although the computer is supposed to compensate, it can only do so within certain parameters. That being said, the easiest way is to drill out the rivets that hold on the tips. With the tips removed you remove the baffels and either leave them out altogether or cut more openings in the, but avoid the last two inches as not to loose all the back pressure. I hope this helps.
