Don't forget the Yoshi slip-on. It costs more, but it is much quieter than the HMF, and delivers every bit as much of a power boost.

yeah that will be fun, fun for me(its not too fun losing if u ask me)lol.glad the shocks are better, bring it to football on monday. we will have to go riding sometime next week.

That quiet core that you can get from HMF doesn't make a hoot of difference when it comes to noise supression.You have to have it to insert the spark arrester though.
I put the quiet core in mine few days ago and it was still loud as hell.Trying to ride at night in a neighborhood hehe.
I definently love my HMF pipe though huge power gains.

thats cool i got a quiet core for free. i only ordered a spark arrestor and it fit it. my bill never said i ordered a quiet core.

How much you pay for the spark arrestor $35?

nothing. i think it was complementary or something. i dont have a record on it in my reciept. it says 210 for pipe, 20.00 for getting in in black powdercoated, 5.00 for 170 mj,18.05 for shipping, -19.95 for joining their forum. total bill was 253.05

That's a great price for your slip on. Glad you like it so much. I felt the same way about mine.
