Frequently Asked Questions
FMF Gnarly vs Fatty pipe for 2-stroke — which should I choose?
FMF Gnarly is tuned for low-to-mid RPM power — better for trail riding and enduro where tractable power and bottom-end torque matter. FMF Fatty (or Factory Fatty) is tuned for peak power at higher RPM — better for MX tracks where you want power in the upper RPM range. For Canadian trail and enduro riding, Gnarly is the typical choice.
Does an FMF exhaust require a rejet on a carbureted bike?
Yes — an exhaust upgrade on a carbureted 2-stroke or 4-stroke typically requires carburetor rejetting to optimize fuel delivery for the increased airflow. FMF provides jetting recommendations for their exhaust systems for each specific application.
