Two Brothers M-5 VALE Slip-On Exhausts

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 M5 Slip-On Exhaust Kawasaki Concours 14 2008-2014 4.7 5 13 13
Titanium M5 Black Series a great choice for my 2010 Concours 14 I wanted an aftermarket pipe that saves weight and provides a sportbike sound. The Two Brothers exhaust delivers in both areas. The pipe arrived in a great package and the fit and finish is top notch. I commute almost 100 miles a day so the sound was a bit too loud for me at highway speeds, but I fixed that with a Power Tip, P1-X. The Power Tip gives a good, deep sound around town but is fairly muted at highway speeds. I wear earplugs on the highway to cut wind noise and I don't even notice the pipe anymore. My only complaint concerns the bracket holding the pipe to the passenger peg. The hole was too small for the bolt so I had to drill it out to fit, which was a pain. Other than that the install was simple and straight forward. I've logged about 4,000 miles with the exhaust in all types of weather and traffic conditions and the durability is good so far. Overall I'm happy with the exhaust, it performs as advertised and looks great. No more heavy, potato launcher stock exhaust (saved 13 pounds). June 15, 2015
Great exhaust option for the Councours 14 I bought the titanium version and really like it. It was easy to install, but I had to drill out a hole in bracket that suspends the pipe from the passenger peg. For some reason it wasn't large enough for the stock foot peg bolt, but it was after reaming it out with a drill bit. Other than that, it was easy to install and fit very well. The VALE system is very nice too, it allows you to fit the pipe and then align the canister before tightening. I had no leaks and it sounds great. I don't think it's too loud, but some folks might. It's deep and throaty as described but not excessive. It would still sound good with the power tip if you choose that route. The packaging is excellent, TBR knows what they're doing and I'm glad I picked them over the Vance & Hines. April 6, 2015
Outstanding Product Great looks. Outstanding note/sound. Huge weight reduction from stock pipe. Lots of questions and compliments on exhaust. May 18, 2015
Outstanding sound! Instructions not clear. Had to refer to you tube. Don't forget to remove rubber center stand stopper from stock pipe. Try not to damage it. Great sound, purchased the silencer but I haven't installed it. Not too loud. March 9, 2015
Not too loud with silencer I bought this mostly for the sound. It installed easily, looks great and saves a ton of weight. It would have been helpful to get SOME instruction for the silencer. It was easy, but there were two o-rings with no guidance whatever. (The two-minute YouTube clip sorts it all out.) I was quite worried about it being too loud, as I didn't want it much louder than stock. With the longer of the two available silencers, I'd say it is maybe just a little louder. In any case, I can't hear it above 45 mph or so. And it sounds great getting there. I think the engine may rev a little more easily as well. It's hard to say much about the durability just yet, but so far I am quite pleased. September 8, 2014
Nice muffler ... the exhaust pipe is something you would find on a mini van. The muffler it has a nice finish and a great sound. Also, the weight savings over the OEM exhaust system is signifigant. But any after market system will be a weight saver over that beast. My only but major complaint is the finish (or lack of finish) on exhaust pipe itself. Its a real eye sore in my opinion. Even the Kawa Concours OEM pipe I removed, has a very nice polish to it. The 2 Bro's pipe has a cheap brushed finish on stainless. The unfinished pipe really draws my attention away from the otherwise expensive (custom?) upgrade I just paid for. I installed the system on a Kawa Concours 1400. I like to think the sport touring and sport rockets, should have an aircraft sleekness to them. This part looks like it came from a Walmart garage. Just my opinion May not bother most riders, but keep it in mind before you plunk your hard earned money down. August 8, 2014
Sound test Concours 14 First of all the stock pipe weighed 20 pounds while the slip on weighed in at 6 pounds so that's an advantage. I purchased a Radio Shack digital sound level meter model 3300099 to measure the sound levels. Readings were taken at one (1) foot from the end of the pipes on the "A" setting and fast sample. Same spot in my garage with the door open for all tests. Readings were taken at idle speed of approximately 1050 RPM. The stock pipe reads at 85dB. The Two Brothers slip on read 95dB. And the Two Brothers slip with P1X power tip sound reducer read at 91dB. Also without the reducer the engine popped quite a bit on deceleration. So, weight loss yes however the noise levels are a matter of my personal preference but I will leave the reducer in. June 3, 2014
Good upgrade for this bike This exhaust has some good sounds. Not too overpowering but when you get on it you can hear it. Makes the bike sound like a beast and a new machine. I May 5, 2014

John R: Remapping is not required if your goal is simply improving exhaust sound. You will still get an improved performance as you dump considerable weight and allow the engine to breath easier.

However, if you choose to do so, remapping will provide additional engine performance.

Jeff L: No - slips right on! The biggest hassle was getting the rubber stopper for the center stand off the old pipe. Came off with some wd-40. Jan 22, 2015
