I sold the FMF which I was very unhappy with b/c it stuck out past the grab bar on the 400ex. the Yohimura isn't even close to level with the end of the grab bar and sounds better.

I am very unhappy with FMF, they should do a little more R&D I think, how stupid can you be to make a pipe that sticks out past the grab bar??

 

so how do they compare to each other in power?

 

not sure yet, about the same right now but I just put the Yoshi on and have to ride it some more to get a better feel.

 

Which FMF pipe did you have

 

Why would u buy an FMF in the first place? They make no power and are just loud noise.

 

the FMF I had was the Q series, I got it used. it wasen't even that quiet...
