FMF or White Bros

Looking for exhaust for XC racing. Interested in aluminum pro and Factory 4 with power bomb. Does anyone have these? How loud are they and do they give good low end power?

I've heard the white bro's have good low end grunt. Go with WB.

HRC kit with HMF silencer is a great combo

I have the HRC kit and the Yosh RS7.It rips and delivers a handful of smooth power throughout the rev range.The Yosh is a little loud wot though!!!

Go with White Brothers. FMF has a problem with their headers cracking.

I have the aluminum pro and my buddy has the factory 4. Both are kinda loud but the wb way out pulls the fmf. It has so much more low end. The fmf is more mid and top end but my quad will still pull him everywhere.

I was thinking about the hmf sport pipe, so how much does the HRC kit open it up and what kind of power gains would you see? Should i go with a different pipe???

FMF and White Bros. are not a popular choice anymore.
go with something else.

There is a post on here called HRC numbers i think. It shows the hp gains and tourqe gains from stock to the HRC kit. It comes with a header that Honda has really done their homework on, so I would stay with it. It also comes with a silencer insert that helps, but an aftermarker one would still be better.
