Two Brothers - Honda CRF450R (2011) - V.A.L.E. M-7 Slip-on Exhaust System

With the patented use of magnesium, titanium, aluminum and stainless steel, and hours of testing we have come up with an exhaust system to win races. Increased throttle response, more power throughout the powerband, and lighter weight all add up to a winning combination for the all new CRF450R.

As an added benefit, all of our off-road systems now feature our exclusive patent-pending V.A.L.E.™ attachment system and X-Lite™ retaining ring. Our stainless/aluminum systems even come with a U.S. Forestry Service approved screen type spark arrestor factory installed!

Our new M7 V.A.L.E.™ exhaust systems feature our exclusive Teflon coated, blunted, cast magnesium outlet and our exclusive X-Lite™ retaining ring. These exclusive Two Brother Racing features not only look great, but also significantly reduce the weight of the exhaust system.

The V.A.L.E.™ inlet design eliminates the use of springs and creates an adjustable mount that is rock solid when fixed in place. The system also features a precision mandrel bent, thinwall s-bend tube, and for a full system, a header pipe custom fit for each model.
