Product Details

Two Brothers M-2 VALE Slip-On Exhaust

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.

NEEDS POWER TIP AS PART OF THE SYSTEM
This review is for the M2 VALE Carbon Fiber exhaust recently purchased and installed on my 08 Suzuki DL1000.

Shipping from Revzilla was fast and efficient. Packaging was excellent. Used Zilla bucks from previous purchases to save on the total cost.

The installation was very straightforward and simple for even novice mechanic. Tools for install included along w Permatex. Look and finish is awesome. I weighed the difference between stock cans w/ downpipe and the carbon fiber cans and downpipe, and shed 8lbs from the bike.

These cans are UNRESTRICTED. You run basically an open pipe with baffling surrounding the end which makes for a VERY LOUD pipe that sounds raspy and no different than the straight pipe on a Harley (if you're running a twin engine). Your bike will run very lean due to no backpressure and that's not good. Warning: If you are buying these cans only, you will need to somehow richen the fuel delivery. I ran the bike two days in stock fueling configuration and the bike hesitated, popped, stalled at idle and only ran well when the throttle was WFO.

The next day I installed a Power Commander V - for the exhaust setup. Without the PCV or an alternate fuel
control system, these cans would make your life miserable and your bike run poorly. After the PCV was mapped for this bike and these cans (Power Commander has the exact map download for this configuration) - I went for a ride and it was smooth and responsive. No more stall or hesitation or excessive popping.

However, it was still WAY TOO LOUD as an open pipe AND was still missing low and mid range power! Two Brothers sells separately 3 variations of a "power tip" which inserts between the end of the can and the end cap to create backpressure and restrict the open ended can, reducing decibles and creating some backpressure. I did not run the pipes with the power tip in stock fueling mode so I do not know if this configuration will work with stock fuel delivery, This power tip (P1X is the one I bought) costs $35.00 EACH and amounts to a basic machined aluminum pipe fitting. Since I needed two of them, my cost with shipping was $70. Once installed, the exhaust noise was tame(er) and the low and midrange power restored.

Installing open pipes on a motorcycle will require jetting or fuel control mapping, but there is no mention of this in the paperwork from Two Brothers. That's OK, I expected it, but others may not. It should be stated somewhere before purchase that this application will not run with stock fuel settings and will require jetting or mapping otherwise your bike runs like junk.

The Two Bros. M2 VALE "system" as ordered is not complete IMO, i.e. no "power tip." I hate feeling like I'm being nickeled and dimed, particularly when so many consumers deem this power tip a necessity. It is a very simply machined aluminum part that costs
little to manufacture. I'd rather pay the extra $70 up front and have it included in the initial purchase of the "system" and not sold separately. Are you listening Two Bros? It makes me hesitate and reconsider future purchases such as Staintune or Leo's.

In the end I am satisfied with the setup and feel like I gained a few extra horsepower and a nice sounding bike with no more fuel surging or hesitation issues. With the power tips it is now tolerable for my passenger on the highway. I gave the overall cost, setup, and performance 3 stars due to the fact that the cans alone do not make this a "system" and should not be advertised as such. You WILL need a fuel controller and the "power tips" to make the "system" perform optimally, a total cost of around $1,200.00. The power tips should have been included in the intitial purchase of the system and some mention of it should made by either Revzilla or Two Bros. that fuel mapping will be a necessary modification to complete installation.

It doesn't HAVE to be loud
I bought mine for a 2014 kawasucki Z1000
This means (because it's a slip on and I didn't delete my cat) it's four into one into two.

Definitely louder than the stock barrels and at first, because everybody online cried over the noise, I believed it was too loud too. But every day that somebody comments on the bike I bring up these exhausts (carbon for me) and I ask em if they think it's too loud. Nope

For an example, after a ride out I stopped and asked a city trooper why the road was blocked off and then we had a whole conversation, without yelling, without me turning off the engine.
Nobody but me thought they were too loud.

NOW. I just bought a 2009 ninja 650r that has the bottom exhaust that's hidden and....if that's a cat attached to the back of it, I'm a monkey's uncle.
Anyways let's say there isn't a cat. it's two into one and with no cat to act as a baffle this exhaust is SUPER loud even with the p1.
I tried it without it......Noono.

To those who say it's too loud I'd say put your cat back on, and to those looking to buy one, I would say keep your engine in mind.

What I mean by this is that my z1 has 4X250cc explosions, while the ninja has 2X325cc
As a result I notice more of a punch with each explosion from the ninja, than from the smoother (and more frequent, because of the two extra cylinders) humm that comes from my 4cylinder smaller-cc-per-explosion z1

In short: some bikes are suited for this exhaust (without gettn everybody in a tizzy-and making you regret it) and some bikes aren't imho
Also unless your motoGP keep yer damned cat on yer bike

Wow
I bought this and put it on my 2008 Kawasaki Ninja 650R and it sounds beastly. My bike no longer sounds like a Vespa. It is so much louder than I expected; any video you watch online does not do it justice.

The exhaust was very easy to install, but the hardest part was getting the stock exhaust off. All in all, it took me about an hour from start to finish.

Thrilled with the result, but a couple of quick warnings
I purchased this system for one reason only...the sound. What I got was a lot more. Installation went pretty smoothly. And when I pulled the OEM muffler out I could see why my stock FZ6 sounded like a Moped. And I was amazed that my poor bike could breath at all through the OEM canister. The Two Brother cans open everything up and the bike can now breath! It runs noticably (albeit only a little) better and sounds terrific.

A couple of quick notes regarding installation. 1) Be sure to make your cut within an inch or two of the blinkers when you are removing the OEM wiring harness. Yes, you will be reusing that. 2) Do not torque the license plate light bulbs too much or the hollow bolt with break. I broke one. Apart from that, installation is a breeze. It took me about 3 hours, but I wasn't in a hurry.

I would strongly recommend this or any other slip-on exhaust replacement for an FZ6. UNLESS, it is important to you to have a very quiet bike - which a stock FZ6 is (IMO).

Great soundtrack!
Got this for my F800GS. First the negatives; It's a bit long, and the the connector pipes fitting over the stock header is too short. Unfortunately, the Aluminum one is SHINY AS HECK. Mirror-like finish . I thought I ordered the dull one, but i guess not.

It sounds amazing. Quality seems top notch. Good price on sale!

I got my money's worth
I installed it on my my 2012 ninja 250r, before I put it on the stock exhaust sounded like a scooter, I was always embarrassed to rev my motor when riding with others. Now my little ninja sounds like a much bigger bike then it did before. It's exactly the sound I was looking for. My money as well spent on this product.

Excellent - but with a few things to remember
Finish and quality is excellent. Really well done. The fender eliminator kit is also really great looking.

Keep in mind you'll have no fender now, so the exhaust / underside of the bike is going to get nasty in the rain very quickly. Hope you like washing your bike!

Every time I accelerate I find myself going "OH YES" however after 15 minutes of cruising I find myself now going "bleehghbhghg" as my brain bleeds from the penetrating drone.

Earplugs help but only so much. The other guys I've ridden with on longer treks hate being behind me. Sorry guys!!
