It is very easy to install which took me about 1.5 hours. Sounds amazingly loud specially after deleting the catalyst converter. Best choice in the market ( to my expectations) and worth every single penny invested in this upgrade. It's Two Brothers or no Brothers!!!! Love it ;)

The fit and finish are top shelf. Easy to install and not to loud gives the bikes exhaust a nice tone.

I purchased the carbon full exhaust system with header pipe about a year ago for my 09 YZ250F and have not been impressed. The mid mount bracket cracked and broke off during a trail ride this week. The end cap top hole broke out because the spark arrestor insert and reducer cone don't fit well together under the end cap. The pipe is too loud (just as loud or louder than stock). I feel bad riding trail with it, but fine for track. All the can bolts came loose at some point, had to replace and thread-lock them. Header bolts keep coming loose. End cap bolts are soft material and strip easy, had to replace those. Pay a little extra for something with better quality. For strictly track use, the system is ok. Still produces good power.

Bought this to repack my M7 and it did not fit in the cannister. After 3 attempts of cutting and stuffing (following multiple TB directives) I gave up. Couldn't believe how difficult it was for such a simple job so I did more research and found out that TB makes an offroad specific kit for repacking the M7. 2 hours, $20 and fiberglass splinters all for nothing. Make sure you get the right one.

I have a 2011 Yamaha Fazer 8. Stock exhaust was way to quiet and mid range needed some help if asked to perform. I Had the Two Brothers Carbon Fibre Black Series installed with a Juice Box Commander unit. First of all its a fantastic looking pipe. It is very punchy and crackly sounding but moderate under 6 grand. From 7-11,500 rpm all hell brakes lose and it is extremely loud and obnoxious. I love it. With the fuel mapping supplied by the Juice box, it has brought this bike to life. I am 53 years old and do not ride hard but when you crack it, it is right there, no delay. Would highly recommend this pipe.

The muffler install was very easy. Very good product and it change the sound compare to the stock exhaust. The exhaust is really loud I highly suggest to people who run a one cylinder bike to buy the p1x if you love your neighbor.
