FMF Racing KTM 350SXF/450SXF/FE Q4 S/A

What you get with this FMF Racing Q4 S/A muffler is a well-built exhaust component designed to bolt onto a range of KTM and Gas Gas off-road motorcycles. This muffler is constructed from aircraft-grade aluminum for its casing and high-strength stainless steel for internal components and the mounting area. It's built to work with either the stock exhaust header or an FMF header, giving you some flexibility in your setup.

Developed over years of racing, this muffler aims to give you the most sound output possible while staying within strict sound limits. It's rated for a maximum of 96 decibels, with most applications running below 94 decibels, which is important for trail riding and racing regulations. The combination of aluminum and stainless steel means it's built to handle the heat and vibrations of off-road riding while keeping weight down. This muffler is a popular choice for riders looking to improve their bike's exhaust note and performance.

This muffler fits a variety of KTM and Gas Gas models, including popular bikes like the KTM 350 SX-F, KTM 450 SX-F, and Gas Gas EX 450F. It's designed as a direct replacement for your stock muffler, making installation straightforward if you're comfortable working on your bike's exhaust system. You'll want to ensure you have the necessary tools and perhaps some anti-seize compound for the exhaust connections.
