I just ordered mine...and was told basically wait another month it'll prob be in...so I just ordered from another company that has them in stock and they are overnighting it to me so ill get it monday.

Is the HMF any better?? I bought the FMF jet kit to compliment my FMF exhaust and my K&N air filter. Hopefully this will give my vinson some power.

anyone who has put one on what should i expect for gains?

 

the hmf is far better, i have one and love it , i think i am going to buy a yoshi, just to see which i like better, and then either return the yoshi, or sell the hmf.
