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 easy to install and the performance increase is crazy! well worth it
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.
Awesome full exhaust! fatten up your main jet and it pulls super hard! throw a dr. d flex jet for fine tuneing and it turns into a monster! great full exhaust a++
We run this exhaust on our yz250f's. Great power increase over stock plus they sound and look really good.
good quality exhaust and you can feel the 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!
