I agree with the FMF system. I had a Yoshimura and the FMF, by far, is a better set up. Stock sucks!

I think the stock pipe works great. Very crisp power, a good increase in taper towards the muffler for great midrange. A little heavier than Ti for sure. I guess I'm missing out on something in the power department. :banghead:

I have owned both the t-4 and fmf systems on my 426..both are great systems and offer lots of power they just deliver it in different ways...all i can say is the fmf gives more power right of the bottom to mid where as the t-4 shines from the mid and up. for me as an enduro rider the fmf is sweet. for the 1 time a year desert trip for me ill probably want to switch to the t-4.
