dude, i reallt dont understand where you are coming from, imo it is the best low-mid pipe out there, at least for the blasty, they are a 2-stroke legend, and there is a reason they are so popular.. To hate something because it is brand name, which i am getting the feeling of, is ridiculous, there is a reason they are popular. they made the powersports exhaust industry big and produce great products. you cant blame them for not changing anything, cause the motors themselves havnt changed in years. if u dont believe me ask kgibson, his son runs a fmf system on a sweet blasty. hmmm i cant seem to recall what place he seems to always finish in races, oh wait i rember, first.
are u gunna use fmf for a duner or weekend dragger, no, but it is a great trail pipe.
end rant
