Sounds pretty mean

i like the sound of this exhaust on my 07 crf450. The carbon fiber gives the can a clean look and is easy to clean as well. Coupled with a power filter from twinair and rejetted the bike has absolutley came alive.

Great Product

great product easy to install and the performance increase is crazy! well worth it

2008 YFZ450

Installed two bros m-7 complete system on my 2008 YFZ450. Also did a boyesen quickshot 3 accelerator pump cover and the "cam mod". Woke my quad up big time, sounds great, It is loud, So the only thing I can say is if you do not like to hear your pipe, don't get this one.

Big power increase

I just replaced my jardine rt99 exhaust with TBR M7 and i'm very impressed! Went on quick and easy, just wish i didn't have to take off the end cap to take out the spark arrestor. This pipe gives a lot of power! I love it, and strongly recommend it!

You have two mufflers showing a carbon fiber and a aluminum body. What muffler comes with a full exhaust kit? Thanks

A: For your 2016 yfz450r SE this would be an aluminum exhaust. Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

Q: Couple questions?
2 years 5 months ago
First will I have to get an EFI tuner with this pipe? (2014 yfz450r) and when I get the exaust will it hurt the bike to run it without a tuner in the mean time? Second what is the size of the header compared to my stock header, just wondering if it's worth getting the fully system as my stock header is already a fatty from factory. And finally the picture shows the aluminum finish with no other options, it will ship with the carbon fiber finish right? Or is it out of stock? Thank you in advance

A: Many of the items we stock are available for a wide variety of applications. A single stock photo may be used to represent many items on our website. If you have profiled your ride, you can rest assured that the part ordered will fit your application. 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 .If you have any questions please contact one of our sales professionals for assistance.

A: Typically after installing a full system aftermarket exhaust, you will need to re-jet your carburetor. 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. After installation I would recommend taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.

Q: For 2010 Rmz 250 Is it very durable? Where do you see gains...Bot? Mid? Top?

A: This exhaust will be a durable exhuast. Not any different than an FMF or Pro Circuit would be as far as durability goes. The aftermarket exhausts usually help crispen the throttle response and will provide small gains in the powerband. The exhaust systems on the stock bikes are not bad at all, so you wont see huge gains from just changing the exhaust. I have provided a dyno sheet from Two Brothers that shows the curve for this exhaust system on the 2010 RMZ250.

Q: Does anyone know how easily this exhaust will crack or break?
Over 4 years ago
If it end up setting my bike down in a corner will it crack?
MotoSport Staff
Over 4 years ago Location: Portland, OR, USA
A: The carbon fiber exhaust systems will not be as durable as a metal muffler would be. If you do go down, rather than bend like an aluminum or titanium muffler, the carbon fiber will crack or break. Keep in mind the carbon fiber cans also require a much stricter re-packing schedule. If you do not keep the muffler fully packed at all times, the carbon fiber can get to hot and become very brittle. Truthfully, there is no performance gain except for a small weight savings when using a carbon muffler.
