Comments about FMF - Fatty Pipe (Yamaha):
I have a yamaha yz 125 and bought this pipe. It gives no noticeable differences in power, torque, etc. Dents extremely easily when riding and it is hot because it is so thin. I know many people who have pancaked this pipe without hitting hard. I set my bike down in soft sand and pancaked this pipe as well. The stock pipe is much more heavy duty and I would highly recommend staying with it unless you ride track or invest in a pipe guard if riding trails.

Comments about FMF - Fatty Pipe (Yamaha):
Perfect exhaust for riders who like a smooth performance. It makes more power then stock. without being agressive. The gas response is very good, you do not have to use the clutch to blast out of inside cornes. Material is durable and it has a perfect fit. Exhaust gaskets are pre-installed in the pipe.
