Two Brothers M-2 VALE Slip-On Exhaust Kawasaki Ninja ZX-14R

Each Two Brothers Racing M2 Slip-On features the same high level of quality construction and is designed to be fully-serviceable in the event of damage, routine maintenance or the occasional repack. All TBR’s M series slip-on exhaust systems feature the innovative V.A.L.E. system with CNC'ed aluminum inlets. The V.A.L.E. system is TBR's revolutionary, patented method of attaching the muffler canisters to the mid-pipe without the use of springs or welding. This system allows the muffler assembly - exhaust mid-pipe and canister - to be positioned perfectly on the bike before all the mounting hardware is fully tightened. Once the canister and mid-pipe are properly aligned, the V.A.L.E. assembly locks the muffler canister to the mid-pipe assuring a perfect, leak-free connection.

Two Brothers' mid-pipes are manufactured from .035" thick stainless steel and feature a polished satin finish. They exclusively use 304 stainless steel for its high rust resistance. After a few heat cycles the 304 steel turns a golden amber color, which is the signature of high quality stainless steel. The exhaust note produced by all of Two Bros exhaust systems is best described as being deep and throaty, without suffering from the shrill whine normally associated with other manufacturer's straight through muffler canisters. But this bark would be pointless without a bad bite, so no matter which great sounding TBR’s exhaust you choose they will all reduce weight and deliver additional horsepower and torque.

As the government aka “The Man” pushes for greater emission restrictions, motorcycle manufacturers are forced to make their exhausts heavier and more restrictive. Two Brothers Racing has given the motorcycle community the means to stick it to the man with the M Series Slip-On Exhaust.

Two Brothers M2 Dual Slip-On Exhaust Kawasaki ZX14R 2012-2016 4 5 2 2
sounds great, but really loud It was very suprised when I first rode it up my street. Holy cow it was filling my helmet with quite the roar, even though i was trying to be quiet. They showed up well packed and perfect. install was a breeze. You have to remove the little passenger foot guard to pull the bolt out. instructions don't say that, and you sure can't hang the muffler from inside of the frame. July 30, 2014
Just Right: appearance, weight, sound The final results would be 5 stars except that it began poorly. TBR included the wrong size X-clamps to connect the cans to the pipes then took 3 weeks to deliver the right parts. Now that all the parts are in and it is installed, I like it and recommend it. Revzilla did their part right from the beginning. I installed the P1X noise suppressors also, which shows in the picture below that is a close up of the tip of the can. I was looking for improved appearance, reduced weight, and as little increased noise as possible. With the P1X, this system accomplishes all of that. The sound is much deeper than stock but it is subdued enough that I can still hear the sweet mechanical noise of the engine. Yeah! March 11, 2014
