Two weekends I walked away from a WB piped bike and beat a BigGun piped predator by a bike length. Three out of three times. All three of us run the RU 1770 slip on and have the same carb mods. Only difference is I am running a 39 tooth rear and they are still stock. So that tells you how well the HMF pulls bottom to top. Smooth tacky dirt field dead stop to 150yds. Pulled them the whole way. The WB wasnt real fair because the guy is quiet abit larger, it looked like he was hooked to a plow the beating I gave him, but the Big Gun rider weighs alittle less than me. Anybody who says the HMF does not have good performance is lying or just doesnt know the facts. I wouldnt trade it for nothing. We tried to talk the guy who bought the BigGun to get the HMF because of the way it performs but he wouldnt listen now he wishes otherwise.


BUT, if noise is an issue look elsewhere because it is loud but has a great sound in my opinion.

 

The HMF is a nice running silencer, but they need to address the noise concerns....great performance though. [img]i/expressions/face-icon-small-smile.gif[/img]

 

im looking for a sound acceptable exhaust system, either full or slip on dont matter, full costs more but i can just save longer. so HMF is outta the question, how loud is white bros? and any sites that sell HPD pipes? i cant get the main HPD site to load. and whats this jet hot coating i hear about lol? THANKS a ton

 

I have a HPD pipe on my scram and love it sounds good!! I dont know how the one for the pred is but if its built like mine you will like!![img]i/expressions/face-icon-small-happy.gif[/img] try this link---------->HPD

no prob [img]i/expressions/face-icon-small-cool.gif[/img]

 

I have the New FMF Factory 4 Ti systems. It works great

 

so far a have only tried white brothers slip on open ended there wasnt any thing wrong with the performance as long is it was open ended. it would fly. but now i have a hpd full race my opinion is there is no match, mid rang and top end it pulls like a rockit. and its sounds good. the white brother was to loud for me i guess im getting to old.
