does anyone know the jetting for the aaen power race pipe for the predator?is this pipe better than the white bros powerwise?any help is very appreciated.

 

aaen said to expect a 7 HP gain but i dont like aaen and i dont dont like the "expect". i called WB and the said there polaris pipe adds 1-2.. most people say thats bull and i think so too.. but WB told me that. the hmf adds 5 for 220$ and the biggun adds 5-6 at 330$.
but with whatever pipe you go with your prolly gonna wanna go with a 157.5 or a 160.
i have a the biggun with a k&n and uni airbox vents and i put a 162.5 in and she runs puff.
