i would go with a sparks or HMF over a duncan if you were to get motor work,but dont get me wrong from what i hear duncan is a very good pipe

Posted by: Dirt Merchant

it came HIGHLY reccommended from a local shop.. the guy that owns the shop is a pro rider, so i kinda value his suggestions, but just wanted to see what everyone else thinks

i never said it wasnt a good pipe,but has he ever tried a HMF or sparks?i would reccomend those if you are going to do motor work
its just another reccomendation,but i love my HMF pipe,its still so easy to pull up the front end even with a + 1 1/4 swinger

Posted by: Dirt Merchant

The fatboy is the ONLY way to go when it comes to exhaust for any of the sport atvs. The dealer says in a 300 yard accel run the fatboy will give an average lead of 20 bike lengths. I race at mobile int. dragway and found i was always getting run down on the top end with my white bros. But when i got my full exhaust from fatboy i said goodbye to being run down. It will run in the sevens with the mods i have but with a bore kit and some other mods i should be able to get into the sixs. But if you want some serious get up and go from an exhaust get the fatboy system you get a free jet kit with it to. Hope you enjoy the fatboy
