hey predman, come out from under that rock, it is not the same pipe as the pure polaris. The pure polaris slipon that white brothers makes for them is an e-series, the exhaust I am refering to is the e2-series, two totaly different systems, the e2 series is not yet available, but it will have a headpipe and a totaly different silencer design. when you saw the pictures of the e2 at rocky mountain, how did you miss the original e-series right above it? I'm not trying to be a jerk, but you really shouldn't pass false information, you cannot say which is louder or going to make more power, you have not seen or heard the e2 system on a bike yet. It is much more than a different sticker.
