Two Brothers M-7 VALE Slip-On Exhaust Kawasaki KLX250S / SF

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.

Two Brothers M-7 VALE Slip-On Exhaust Kawasaki KLX250S / SF 2006-2014 I love the new M-7 Exhaust :) It really opened up the bike. It bolts up to the stock header with no issues. However I had also bought the new FNF power bomb header and the exhaust is 1/64 of inch to big. After a small relief cut in the header and the stock clamp it's perfect. If you do plan on doing allot of street riding I would definatly recommend that you buy a P1X power tip with the exhaust. It will take the exhaust from insanely loud to just loud. June 2, 2014
This is a good exhaust This muffler is a great product. Was easy to install, sound was a little loud. Improved to throttle response of the bike. looks good.Purchased the extra tip to make it not so loud, but I would like it just a little softer. I know the exhaust is for off road, but I ride 99% on the street. I can live with the sound.Mellows out at cruising speed. Overall I like the muffler. July 15, 2014
Great product The two brothers m7 slip on is a great addition for the crf250l.It looks and sounds great.I consider it a safety feature while buzzing around in traffic. June 17, 2014
Nice n loud!! Looks good and made well. Easy to fit.and tucks in nicely behind the plastic work. Sounds a lot better than the stock. It is loud and referred to here now as the 'Neighbour Hater' but the add in Power tip takes a little of the edge off. I'm happy and would do it again. Still tweaking the other parts but the bike feels a fraction better. June 9, 2014
Looks and sounds Awesome ! This pipe only took about ten minutes to install ! December 24, 2013
Easy Install, Big Difference Simple instructions, easy to install, doing the rest of Dave's mods and adding the slip on exhaust really made the bike rip. January 27, 2014
An Exhausting Summary... Ok, I've put off doing the review till I had put some miles on my KLR 650 with the Two Brothers Exhaust.... Now it's time. I had my mechanic do the install though it only took him approx. 15 minutes (I don't have the proper tools) as per his words "It's a nice fit and easy setup"... PROS: Additional torque in the low end, quicker response, and the Carbon Fiber model looks and stays pretty cool! CONS: Decibels!!..This sucker is Loud!(well, louder than the stock by a fair amount)... Get the 8-9 Dcbl sound suppressor! (Unless you hate your neighbors) Revzilla I believes sells it. Loss of MPG.... I'm averaging about 37-40 mpg now..mainly due to the fact I needed to have the carb rejetted and tuned for the new exhaust system.....(fuel injection systems might not be as bad) Overall, I'm happier than a pig in mud with the new exhaust! An added benefit of the louder exhaust is I'm "Heard" on the street and Highway by other Driver's....Anything that alerts people who are encased in 1 ton plus of metal and 4 wheels of me being on the road with them...is a major PLUS!!!

Upgrade! I changed out my stock exhaust on my 2010 klx 250. It was a big improvement in sound and there's a bit more pep when shifting thru the gears. The bike def feels more aggressive with this upgrade. I considered buying a bigger bike but I am glad I tried this exhaust first. I will absolutely stick with it a while longer because I love the sound it makes without being abnoxiously loud but louder than stock. My guy friends installed it by the time I was finished with my beverage so I suppose it was easy for them. Bonus :) June 6, 2013

Jeff D: not necessarily, it may help if you tweak the carb in other ways rather spending big bucks for a re-jet kit i put 2-brothers on my klr 650 and did what they call a 22cent mod to my carb basically bought 2-washers to put on the carb needle and drilled out the tother hole on carb to 7/64s and leaned out carb mixture 1-turn. results great response in throttle more tork and bike sounds great pull up your bike type on u-tube iam sure youl will get all kinds of ideas for you bike and iam sure revzilla has pretty much all you need to do the job right and at great prices too got my exhaust in 3-days. good luck and good riding. jeff Mar 7, 2014

justin s: If Its anything like the xr's you will want to jet it, they come extremely lean stock to meet emissions, i also changed to a foam filter, and pulled the snorkel off so it could breathe more. I also ground the inside of the header pipes to open up the flow a bit. Look up uncorking your carberator, you may get away with just a fuel screw adjustment. Mar 6, 2014

Reden B: Need to rejet your carb if your engine is running either rich or lean. After you installed your new exhaust, test run your bike then check your spark plug. You can determine that your engine is running rich or lean. If still normal color, i think no need to rejet. I hope this will help.
Ride safe. :-)

nathan p: Maybe not ,, but rejetting it will make the Bike run WAY WAY better. If you are looking for performance upgrade , Rejetting it will do more than the pipe will. Mine would not Idle with stock or this pipe until I rejetted it. You will not gain much from doing the pipe alone , except Bad@ss sound. BUY IT ! Mar 6, 2014

Martin M: As Ed mentioned, this is a fairly major change. Rejetting and tuning the carb is the other half of your torque and performance.... also, (depending on how many miles and time in the dirt) think about doing a through tear down and cleaning of the carb since it's going to be off the bike.

Ed M: It's always a good idea to rejet your bike after you've done anything major like exhaust I recommend a JD jetting kit Mar 6, 2014
