Hey guys I have a 2005 yz125. I am curious to which system I should get. Any input would be great. Thanks!

A guy was doing independent testing WITH a dyno on a bunch of two stroke MXers. What he found was that the FMF pipes made the best peak power, but were slightly down through the low and mid. The Pro Circuit Works pipes had slightly less peak power, but consistently made the most linear gains, and would most likely make for the easiest to ride power curves.
