Dope. As in in terms of the power gain?? i got my class 2A 1.5 years than my friends. They told me that Micron is good. Due to my delay in 'license-getting", i had never tried a Micron pipe before. But i got myself a fire spec, i find that it is lighter. i compared the power between both but i believe that weights on a bike can KILL your bike performances. Still, its the rider's skills too. However, i read magazine and found out that the Micron Company has gone bankrupt. So i believe its super rare to test the performance of micron with other pipes nowadays.
