Just looked at there site & there claiming that there full-exhaust systems makes 7hp. Is there any truth in their pipes or does someone else claiming such gains?

 

Im not sure myself. I was looking at their pipe a long time ago. Due to college and all that good junk I havent had the extra cash to put out for my toy. But if you happen to go this route please post I am very interested in finding out myself. I can say I have looked at their pipe's for the 400ex and they seemed very well constructed and looked good. The only thing is most of the riding I do is recreational so noise comes into the picture! If anyone has any recommendations for a good pipe that isnt too loud let me know! =-) I probably didnt help much but I thought Id add my 2 cents about how they looked in person. Hope you find what your looking for!

'01 Blue Raptor- Still stock

If anyone has any info about a possible Blue '03 Grizzly coming out for the US let me know! I sold my '99 Wolverine in hopes of a Grizzly but after seeing some of the Canadian Grizzly's in Blue I wont take a Grizz unless its blue!

 

just installed one of there slip on. very well made pipe. best i seen in person. welds are very clean.
not sure on sound yet since im ported my head. and working with the cams.

I had an HMF on my raptor and it was definitely loud, but where I ride it didn't matter. I think HMF offers a quiet core as well. They manufacture a quality exhaust system in my opinion.

 

FoxRunner,
Been happy with my BigGun mainly because of the optional quiet core. I don't use it much but when I need to it's alot quieter.

 

Is it tolerably quieter with the quiet core? Thanks for the input! I really do appreciate it!

 

I think it would make our local DNR happy, but I haven't had it checked with a meter. It is considerably quieter, I guess it is personal preferance, I like it loud if no one complains (they're hard to hear when I'm on the gas!). Its a real nice looking system also.

 

The HMF full system works best with a piston and cam.Iam going to put one on my 735cc grizzly next weekend.
