Two Brothers M-6 Dual Slip-On Exhaust Kawasaki Ninja EX 250

Slip-On exhaust systems replace your existing “s-bend” pipe and exhaust canister. Two Brothers' s-bends are manufactured from .035" thin wall stainless steel. They then polish them to a satin finish. Two Brothers' uses only #304 stainless which will never rust. 

After a few heat cycles the steel turns a golden amber color which is the characteristic signature of high quality stainless steel. 

These systems not only add horsepower but also can drop significant weight from your bike. This type of canister can be mounted in the original canister position or in a “high” mounted canister position depending on the bike.

The entire line of TBR M Series canisters feature the same high level of quality construction and are designed to be fully serviceable in the event of damage, routine maintenance or the occasional repack. Two Brothers Racing's V.A.L.E.™ slip-on exhaust systems and flange-on systems feature CNC'ed aluminum inlets. These special designs provide for ease of maintenance as well as simplified construction, which is what a premium performance product is all about! The exhaust note produced by all of their Top Level™ 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.

V.A.L.E. = Variable Axis Locking Exhaust The V.A.L.E.™ system is TBR's revolutionary and patented method of attaching their muffler canisters to the exhaust tube without the use of springs or welding. Their V.A.L.E. systems allow the muffler assembly - exhaust tube and canister - to be positioned perfectly on the bike before all the mounting hardware is fully tightened. Once the canister and exhaust tubes are properly aligned, the V.A.L.E. assembly locks the muffler canister to the exhaust tube assuring a perfect, leak-free fit.

NOTE: This exhaust is CARB compliant. Please check local laws before purchasing. Some modifications may be prohibited in some states.

The best purchase I have made! While some other people may have had some issues installing, I had almost none. I am 19 years old and have almost no experience with car or motorcycle repairs or modifications; and for me, installing these was a breeze! The steps are crystal clear, which there are literally less than ten steps, and it only took about an hour! As long as you are careful and follow the instructions, you should be able to install these with no issues. I gave 'Finish' a 4/5 stars because while the exhausts look good, they are definitely not amazingly sexy. But for some, you may not want flashy or odd looking exhausts. Still, they are a huge step above the stock exhausts. January 21, 2015
Not quite exact fit but good enough I recieved my slip ons to find out that the fight was sloopy. I ended up using oem gaskets and expanding the pipe a little to make a snug fit. Slight mods like that are usual for aftermarket parts. Overall still satisfied. January 11, 2015
noticable change in performance. Pros- 1. The new cans are about a quarter of the size of the stock ones. And half the weight. 2. looks amazing. 3. Sound amazing 4. The bike is definitely breathing much better. Notable change in the throttle. Cons- Install---the left pipe to start was about an inch to short so to compensate u had the play with the clamps on the slip on. On the clamps….ok um huge!!!! Took some serious muscle to get them tight enough to stop all exhaust leaks. Overall— They are awesome and definitely work. Great value for the price. And the install really isn’t bad for the mechanically inclined. If you’re not I recommend taking them somewhere to be installed.. December 27, 2011
