People can say what they want about seat of the pants testing vs track times vs dyno runs. I think the dyno runs would show the more accurate comparison by removing a lot of other factors such as rider weight, ability etc. But it does essentially come down to what the riders experience with the product is. I do completely disagree with the appearance comment though. I think CPIs look better ( not that the snipers don't look good). But you are right in stating that that it is hard to justify ditching the cpis and coughing up the extra cash when the CPIs are still great pipes. I think these pipes would have a lot more people using them if they were comparably priced to CPI and Shearers. I sure as shizzle am not about to drop that kind money down on a set of pipes when CPIs are perfect for my riding. If I could get my hands on a new set in that $550 range, I would slap em on my machine for sure and give em a try. I think for these pipes to really go anywhere the price needs to be adjusted. I do not doubt that the pipes are good, I am just not convinced yet that they are great. Everyone just wants to see what the real deal is with these things, thanks for the honest opinions and comparison JD
