i was just wondering how the numbers compare with the big gun full system and HMF's, on HMF's site it says that it will be a 8 hp gain i cant find any numbers on the big gun. so does anyone know the numbers on big gun??
thanks

 

Welcome to the forums...

I too have looked for big gun numbers,never found any...

After many hours of talking to people with both systems, I'm going with HMF,,,, from what i hear its a better all around system...

 

thanks for the reply,

Does anyone on here have the full system HMF... or rode with anyone who has it?

thanks

 

you can go wrong with either... both on the loud side.
i think HMF has the best customer service around.... very nice people to deal with.

 

Pudljumper ran an HMF slip-on last summer (has since switched to a YFZ). The silencer ran great, but the sound, even with the quiet core wouldn't pass our districts racing sound checks. The White Bros/Pure Polaris is one of the most sound controllable systems around. I witnessed a lot of frustration today at our districts opening harescramble. YFZ's were the worst. If you don't have sound testing where you currently ride....beware...it could soon be on it's way. Buy what you want, I know that everytime I show up to race, or ride in a State/National park, I won't be going home right away. [img]i/expressions/face-icon-small-smile.gif[/img]

 

I understand what ur saying about the noise but i just want to get the most hp for my money..
thanks for the replys

 

www.HPD-inc.com, for a powerful full system.

 

ive looked at that pipe before didnt find any numbers.. do u know where i could find any on it? and maybe a picture of the silencer ill i can see is the pipe,
thanks

 

Check on predatorowners.com. And search for "hpd" "exhaust" Theres a fella on there who has a pick of his HPD. I personally think it looks very cheaply built

 

ditto... i saw one at southwick... looked cheap.
