Can HMF pipe be adjusted/tuned like the supertrapps.
And how much spunk does this pipe and with and without jet kits and aftermarket airfilter

 

Go to Highlifter.com and you can punch in your machine and see a dyno run chart on your machine with and without the power kit..usually about a 20% increase in power. The absolute cheapest place i have found to purchase the kit with pipe is ATVOut fitters. They are located in Greenville ,sc. and will ship to your door. I ordered my performance kit yesterday as a matter of fact for my Foreman . I have a couple of friends with this kit and the hmf pipe and they say it really woke them up!! I dont think the hmf pipe is tuneable but according to the dyno charts it makes just as much horsepower as the supertrapp.
