I'm curious what ecu and intake your running for the Yoshimura to be less powerful?...What condition was the bike fitted with the Yoshi in? Stock porting on both bikes?.... Both bikes dyno tuned...if not you're really aren't going to get a good comparison...

The FMF sticks out to far and has really cruddy fit and finish....I have owned both pipes but never used the FMF RCT.
