FMF Gnarly Pipe Exhaust System for KTM

The FMF Gnarly Pipe is a performance two-stroke exhaust expansion pipe (also called an expansion chamber) built for tough off-road riding. It is designed to boost low-end and mid-range power, which gives you better tractability, throttle response and grip on technical terrain.

Key Features:

• Low-to-mid-range power focus: Adds tractor-like torque to your two-stroke. It helps most when you lug through tough sections or climb technical trails.
• Heavy-duty 18-gauge steel construction: Holds up to rocks, downed trees, crashes and long off-road use. It resists dents better than a typical stock pipe.
• Tru-Flo stamping process: Gives the pipe a precise fit and consistent performance.
• Works with stock or FMF silencers: Lets you upgrade the pipe on its own.
• Handcrafted in the USA: Backed by FMF's exhaust experience, which goes back to 1973.

The Gnarly Pipe suits riders who want stronger, more usable power and a pipe that lasts. Choose the correct part number for your model and year from the available options.
