Two Brothers M-2 VALE Slip-On Exhaust Yamaha R1

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.

Best slip on's ever! Hands down!
I purchased the two brothers not really knowing about how awesome they were. I've put them on and just broke them in. It's been about 1000 miles. They sound amazing. The tone is perfect. They don't hear up, infact you can clearly hold your hand on them right after the ride and they are not hot but slightly warm. Again, the best thing is that my bike sounds completely different than the rest with the black series on.

I just bought a two brothers exhaust system (BLK series) for a 2007 Yamaha R1, but Im not 100% sure on how to install them. I searched on YouTube for videos, but nothing.

Any advice/videos?

BEST ANSWER: You made a great choice! I love mine. I bought and had the same problem. I've never done any mods to my bike before! It was so easy. It took me like 2 hours because I took my time. All I did is follow the instructions that come with the package and you'll be good to go. It's super easy.
