The entire line of Two Brothers Racing M Series canisters feature the same high level of quality construction and are designed to be fully serviceable in the event of damage (replacement parts are available separately), routine maintenance or the occasional repack. 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 TBR's 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.
- All of the canisters perform and sound the same, they are simply different shapes.
- They all incorporate Two Brothers exclusive technologies and premium construction materials.
- The shape and orientation is normally determined by Two Brothers R&D department, based on a performance criteria check list.
- All aluminum systems include U.S. Forest Service-approved spark arrestor.
- Notes: Two Brothers Racing products are designed and sold for racing use ONLY. This product is NOT legal on public roads, streets, or highways. Image for reference only; canister orientation and size may vary depending on application.
Slip-On Systems - This type of system replaces your existing "S-bend" pipe and exhaust canister. TBR's S-bends are manufactured from 0.035" thin wall stainless steel. They then polish them to a satin finish. They use 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 and the available applications.
It's loud but it does get quieter after you break it in.
The exhaust sounds great and is easy to install, but no pipe clamp to go back to the the existing pipe on the quad. I purchased a clamp to put there. Kind of a janky design in my opinion. If they would change that so there is an exhaust clamp there, it would be a high quality add-on.
I own several ATVs and this is the best muffler ever. I have it on all of my ATVs and it sounds great and looks great. One of the best company's to buy from.
Purchased for my Suzuki Z250 installed easily and quickly, approx 30 minutes. Sounds Great too.
Just got my M7 for my 2008 Yamaha WR450F. There is no way to connect the head pipe to the pipe that comes with the Two Brothers exhaust pipe. The pipes are different sizes and there is no clamp or composite "donut" provided to allow the two pipes to connect properly. I have this same exhaust on my other bike and it came with everything needed for a quick and easy install.
Sleek looking and mean sounding exhaust. No problem installing it on my TRX 450r; came with all the right tools for the job. Instant pickup from the quad. A must have if you're looking for a reliable aftermarket exhaust.
Tried to get it on my bike. Didn't fit right. Called customer service and the said I needed extra parts or to get some clamps to get it to stay on. Was very disappointed it didn't come with everything needed to get it to stay on my bike. I returned it.
It looks great and sounds great. There was some modifying that had to be done but nothing to hard. i love this company and they are great to deal with if there is any problems. Love the sound is very deep and mean sounding. will buy again.
I purchased the two bros m7 slipon for my 05 yfz 450 and I put it on nice and easy and instant powergain but I suggest getting stage 2 up jet kit but I love the pipe till this day
i just got the two brothers exhaust in the mail and could not wait to put it on! once i did... WOW! my bike went from sounding like a moped, to sounding like a moto gp bike! (well, to me atleast). i cant go down the street without waking up the neighbors it feels like. highly recommend this, and its alot cheaper than the two bros website. guaranteed to put a smile on your face!:)
its a great exhaust. Great gain in power. good powerful sound that carries. i also added the sound diffuser. not as loud when i'm just cruising, but still great sound when i get on it.
This is the real deal. The M-7 sounds amazing and has the power to go with it. Holds up nice over a period of time. If you want an increase in power then grab this exhaust wile you can.
There is not a specific setting I could give you for jetting your bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike
Normally when installing a slip-on only minor changes to the air/fuel ratio are needed, if any at all. If your bike is currently running properly, likely you will not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the machine to see how it is running then decide if you need an purchase an aftermarket EFI tuner .
