Two Brothers M-2 VALE Exhaust System Kawasaki Ninja 650 R 2012-2013 This system completely replaces your existing exhaust system. This not only adds horsepower, but also can drop significant weight from your bike. Two Brothers' builds their header systems as a complete unit. Their finished system flows better at the collectors, makes more power and does not vibrate on the bike. TBR's superbike stainless steel headers are manufactured from .035 thin wall stainless steel. They then polish them to a satin finish. The ductile quality of stainless steel makes it possible to produce extremely light and strong headers. TBR uses only premium #304 stainless which will never rust and after a few heat cycles will turn a golden amber color which is the characteristic signature of high quality stainless steel. This type of canister can be mounted in the original position or in a high mounted position depending on the bike. NOTE Please check local laws before purchasing. Some modifications may be prohibited in some states.
