I did the bafflectomy, and liked the sound...didn't mind the decrease in low-rpm torque. Then, I put a PC-III on it...MUCH better. THEN, I put turn-down ends on the pipes. WOWEE! I literally have to be aware when I take off fast from a light, as the front wheel will lift if there is any excuse to do so. Hit the ridge in the middle of an intersection in 2nd the other day, and the front wheel didn't touch back down until I had gone over the three lanes on the other side of the ridge (it was probably only up about 6-8 inches the entire time, but, it was a surprise). I'm very happy with this setup.
