Jean Paul recommends the 2620 pipe. We've tested the 2601 & the 2620 pipes and have found that the 2601 gives better bottem-end power. The 2620 is smoother with a little better top-end. For USA tracks, you should have both plus the different length headers so you can fine tune the powerband to the track.
