Product Details

FMF Racing is well-known for making performance exhaust systems, especially for off-road bikes. This Factory Fatty pipe is built for your KTM 105 SX, giving it that distinctive FMF sound and improved performance. It's designed to help your engine breathe better, which can make a noticeable difference when you're out riding.

The seams on this pipe are hand-pounded, which creates smoother transitions inside. This helps the exhaust gases flow more freely, contributing to better engine performance. The header section is made from 19-gauge steel for durability, while the body uses a lighter 20-gauge steel. This lighter material helps achieve the characteristic 'Factory' sound that many riders look for. It comes with the necessary O-rings for installation.
