FMF Gold Series Fatty Exhaust Pipe In great condition! With well over 35 years of racing experience behind it, the Fatty pipe delivers race-proven performance. The Fatty broadens and smoothes out the power curve while boosting gains throughout the entire power band, more low-end, more mid, and increased over-rev. No matter what type of riding you do, the Fatty has the benefits you're looking for. - More tractable power, improved throttle control. - Provides power gains throughout entire power band. - Carbon steel with a nickel-plated finish for maximum durability. - FMF Racing's Tru-Flo stamping process ensures a perfect fit and optimum performance. - Can be used with FMF or stock silencer. - FMF's most popular 2-stroke pipe. Came off of a 2017 KTM 125 SX (see last six pictures). I believe this will fit the models listed below or but please do your own research and confirm fitment before purchasing.
