thank you again everyone for all the good info. sooo.. if I change out the fmf for a pipe that is a better top end pipe, would I lose the bottom end umph that she has now? I do all trail riding in the desert, and mountainous trails and hillclimbs. that is why I got rid of the banshee, it just didn't have the bottom end pull that I needed to be able to slow her down a bit when climbing nasty rutted out hills. I do not want all of my power band to hit up top so that I have to scream up a hill. as fun as it can be, I do not have a death wish LOL.
