Fits 2017-2019 KTM 150 XC-W 2016-2018 KTM 125 SX 150 SX Husqvarna TC 125 (see detailed fitment below)

The Factory Fatty is a harkening back to the “works” or cone racing pipes that were once used by the Factory Dirt Teams. It has many of the same characteristics with its craftsmanship and quality of materials. The Factory Fatty™ Pipe broadens the power curve and makes it smoother while boosting gains throughout the whole power band, more low-end, more mid, and increased over rev. No matter if you're a Safe Sam or a Dangerous Dan, the Fatty has the exhaust benefits you need with the great look of a raw steel finish.

NOTE: raw steel needs proper care and maintenance. There is no coating to prevent rust so it's necessary to coat it ourselves. A good layer of WD-40 after washing will help preserve the finish. If rust does pop up you can usually get it out with a Brillo pad. Do your research on this matter as there are a number of different techniques and dos / don'ts.

• Lighter 20 gauge steel used for the body of the pipe.
• 19 Gauge steel used for the header portion.
• Includes O-rings on most models.
• Hand pounded seams for smooth flow transitions.
• O-Rings Included

Finish: 

•  Raw Steel (finish requires maintenance described above.)
