Two Brothers M2 Exhaust System Kawasaki Ninja 250R

Are you looking to feed your horsepower addiction? TBR has your fix. Introducing the Two Brothers Racing M2 Exhaust System. Constructed of high-flow stainless steel headers, midpipes and your choice of muffler material, this exhaust delivers performance, aggressive looks and a snarl that is unique among its competitors

The headers are manufactured from .035" thin wall #304 stainless steel tubing which are polished to a satin finish. TBR exclusively uses premium #304 stainless for its ductile quality making it possible to produce extremely lightweight, yet strong headers. After a few heat cycles the pipes will turn a golden amber color, the signature characteristic of high quality stainless steel. Additionally, the stepped design creates a vacuum effect which aids in the efficient evacuation of exhaust gasses. The result is a lightweight exhaust that produces horsepower and torque gains throughout the powerband.

Encompassing all this extra muscle is Two Brothers’ trademarked V.A.L.E. system with X-Lite retaining ring and premium M2 muffler featuring TBR’s signature cast magnesium end cap. Once the canister, mid-pipe and headers are properly aligned, the V.A.L.E. assembly locks the muffler canister to the mid-pipe ensuring  a perfect, leak-free connection. Each M2 muffler features the same high quality construction and is designed to be fully-serviceable in the event of damage, routine maintenance or the occasional repack.

With an exhaust system this capable, the sound has to match the performance. The Two Brothers M2 Exhaust produces a deep roar thanks to its spiral-wound perforated core technology, giving the Two Brothers M2 Exhaust System a bite as mean as its bark.

Awesome looks and sound
I have not ridden the bike yet as I need a tune since I changed the air filter at the same time. The sound is awesome, gives the bike much more bark than it had before. Be warned that this exhaust is very loud. After riding for awhile I will decide if I need an insert or not but right now I like the loudness and the rumble. The exhaust looks great too, I love the black carbonfiber look and the pipes are put together very well. Great addition to the bike.

Does it come with new gaskets?
A shopper on Aug 28, 2013
BEST ANSWER: Yes, my carbon fiber exhaust system for a 2009 FZ6R came with new gaskets and everything else that I needed to install the full exhaust system from the engine all the way back. The juice box is also a "must have" item. Combined, this is now an entirely different bike. I couldn't be happier.
