I have an XR's Only Competition Exhaust on my reasonably modified 650R. I am please with the power but the noise will keep me from racing a few strict events this year. I am considering the FMF Q2/Power Bomb combination to get me to 96db. I am hoping to get feedback from any of you with experience using this FMF combo on a 650R, especially anyone who used exhausts other than stock prior. If it's going to put me back to near stock I will save the +/- $650 and skip those races. Please advise.
