Two Brothers M-2 VALE Slip-On Exhaust BMW F650GS / F700GS / F800GS

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.

frank g asked: I have a 2005 BMW F650GS twin spark single I'm prepping for the TAT. Does this also fit the 2005? And is there a matching tool tube to put on the right side once the exhaust is replaced with the single pipe? Oct 3, 2015

Christian G: It best to say it 'can' fit. The slip on its self will fit under the rear of the bike, but you will need to get a custom mid pipe made in order for it to fit. This particular product was made for the f650gs twin. I took the chance when I bought it and found out the hard way, but kept it anyway after getting a midpipe made because of how awesome this two bros sounds. Oct 3, 2015

A shopper asked: Can I add a spark arrestor to this Exhaust? Nov 21, 2014

Gerald H: Yes with no problem. I added the sound supressor and the spark arrestor screen under it with no problem. I did have to angle or twist the exhaust counter clockwise about 20 deg. to miss the luggage rack. Hope that helps. Nov 21, 2014

jesse f: It's basically a straight pipe, so I don't think you could add one unless the spark arrester is the same diameter as the pipe feeding the muffler. Nov 21, 2014

A shopper asked: Hi there,

With the 2014 G650 GS they appear to have two pipes. One is a cat converter and the other the exhaust pipe?

When buying from you, do you supply the two or one?

How does it work, was the old model the same?
