Figured it was time to spend the money to get a little different sound from my beastie, so I put on the middle of the line Two Bros. pipe a couple of weeks ago, with the P1X power tip. A little bit of a shock after having gotten used to the OEM over the last few years. I wear plugs and can't really tell the diff on the highway, but definatley can tell when starting from a dead stop. Going a a trip this weekend so will give more of a report later. BTW, I wanted to get a smaller Yoshi, but could only find the one that sticks up about 8" above where the top of the existing OEM pipe stops.
