I know alot of you may disagree, but I debaffled my 09 VN900C SE just the way alot of you have on this site. I will say it really does sound pretty darn good, but it its pretty loud. Actually its really annoying at Highway speeds, my ears were ringing and I was wearing a full helmet. Around town, it sounds really aggresive, has a nice rumble and good bark to it. BUT, I lost ALOT of power! Yes, I really did. I noticed the midrange is almost dead. Almost feels like it running out of fuel. My bike has 350 miles on it and there is nothing wrong with it. I thought the cat converter would cause enough backpressue to keep the engine running the way it was supposed to, but I was wrong. The bike is really slow now, it really made a difference for the worst. I had drilled the baffles before and rode like that for 100 miles or so, and the engine ran the same. No difference noticed in power output. It sounded ok, but to me it sounded more like it had an exhaust leak rather then a nice set of pipes. So that was the reason why I completly removed the baffles. I have the same tank of gas since before I debaffled and after, so its not a fuel quailty issue. The FI light did not come on, no stalling or hesitation or surging, no other problems at all except for the loss of power. And I am talking a noticable difference. So keep that in mind before You debaffle. I am going to order the Big City Monster Baffles Tommorow to give it some needed backpressue.
