well, since mr. kgibson decided to have a hissy fit and leave here, i'll relay his findings............. on his sons jordans bike, he tried just about every pipe out there, including a toomey, and returned to the fmf, as it pulled the hardest in the rpm ranges jordan ran on the dade city mx track, which led to numerous holeshots and wins
if the way you ride, or plan to ride resembles an mx race, but in the trails, the fmf has proven to be a winner
if you give a rats ass, which i don't, if you can beat your freind across a 500 ft. feild, then the fmf probably isn't best for that situation, so yes, there are alot better pipes for top end , but the fmf's do great for low to mid/high power, then fall out of the power band at high rpm's
i say get the fatty, you already have the silencer, and you'll be more than happy versus a stock pipe
BTW...we just picked up a fatty equipped bike yesterday, but have a few things to fix before we can give any ride reports, it'll be my first experience with an FMF, and i can't wait to put it thru the paces here in the trails
