Two Brothers M-2 VALE Slip-On Exhaust Yamaha FZ1 

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: Please check local laws before purchasing. Some modifications may be prohibited in some states.

Good quality and AWESOME sound! I purchased this slip on for my 2012 Yamaha FZ1. My bike sounds like a mean moto GP bike now. Traffic hears me coming and I feel much safer now riding in town. Revzilla got my exhaust to my house very quickly and it came packaged securely. The quality of the carbon fiber black series is great and it looks even better in person! Any video you watch online does not do this pipe justice. It is much louder in person but not uncomfortable while riding at all. Makes your motorcycle so much more fun to ride! I gave 3 stars on install simply because I believe my exhaust was packed with the wrong mid pipe barrel clamp by 2 bros. I called 2 bros and they sent out a new clamp no questions asked! Great service and great product! July 21, 2014
Really good exhaust The only reason why it got anything lower than a full 5/5 is because there is a solid bushing that comes with the exhaust that is supposed replace the stock bushing doesn't fit properly. The screw that is supposed to hold it on to the body doesn't fit through the solid bushing so I just Jimmy rigged myself one out of the old bushings and it fit. I just threw away that solid bushing away. It was useless. August 11, 2014
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. May 19, 2014
Impressive product Exceed my expectation with the product. I had my product the next day. How awesome is that.. May 19, 2014
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! May 1, 2014
Great TwoBros exhaust! I bought this exhaust after doing a lot of research on different aftermarket exhaust and this one ended up being one of the better ones out there for a slip-on. I got the carbon fiber black series model and it looks and sounds great! It definitely gives it a little lower end growl and is louder than stock. It also adds a few horsepower to the bike. The install was pretty easy. The hardest part was getting the servo cables disconnected on my '07 R6, but it still was pretty easy. It took me about 45 minutes to fully install, but it would definitely have gone faster now that I know exactly what to do. The instructions they give are very informative with pictures so you can make sure you are doing everything right. Overall I am very pleased with this exhaust and look forward to using it this season. Revzilla was great as always with very fast shipping! February 21, 2014
nothing short of AMAZING!!! The notes on the TBR are a symphony! In my opinion, its the best sounding slip-on. October 28, 2013
Loud The exhaust install is simple. Can be completed in under 30 minutes. The exhaust is loud! Really loud! Like you can hear it over wind noise at 50 mph loud. But it sounds awesome, so no complaints there. October 21, 2013

A shopper asked: Is it necessary to remap the fuel injection with the installation of just this slip-on for a 06 FZ1? Nov 10, 2013

Kevin W: No. So far I've added the Two Brothers Slip-On (I left the cat in), K&N air filter, and blocked the AIS (this helps eliminate some of the poping noise when decelerating) and the stock CPU had no problem adjusting to these changes. If you do any other modifications, such as an air box mod, flies mod, etc. you will need to remap the fuel injection or you will run lean.

Of course, if you want the full benifit out of any modification, you should have a custom map installed.

There are several discussions about modifications, maps, etc. on the FZ1 Owners Association (FZ1OA) forum fi you need more information.

Also, Copperdawg has several good "how to" videos on You Tube regarding these modifications.

Troy G: If the only thing you change is the exhaust, it may not be a requirement, however you will probably end up with some decelerate popping. I did the Lars intake mod, gutted the cat, and removed the Exup cables with the installation of the slipon, so I also added a power commander to balance it all out.
The FZ1 community has a massive forum (FZ1OA), where the people have posted different "maps" for the power commander based on which mods you've performed, you simply download and upload to your bike.

I will tell you, this exhaust sounds absolutely wonderful on this bike...that deep, throaty race bike sound.

Mark E: I don't think you necessarily need to. I put mine on about the first thing I did, before I had a thousand miles total on the bike. It doesn't lack for performance - I don't hear any popping on deceleration, and there aren't any flat spots when you roll the power on. Even in 6th gear, just a twist of the throttle will result in a strong and steady increase in speed from 60 or 70 mph to 100+ in what seems like the blink of an eye. I would fully recommend the Two Brothers M2 Vale Slip on to anyone. The carbon fiber model looks tight on the bike. Nov 10, 2013
