FMF Factory 4.1 Slip-On Exhaust

Swapping the stock muffler for FMF's Factory 4.1 slip-on is one of the most direct ways to change how a Yamaha Raptor 700 sounds and looks. The slip-on design replaces only the muffler and keeps the original head pipe, so the job stays simple and the rest of the exhaust is untouched. FMF is a long-established off-road exhaust brand, and the Factory 4.1 carries that name onto the quad.

Why riders choose it

• Head pipe stays in place, keeping installation simple
• A lower-commitment upgrade than a complete exhaust system
• Changes the exhaust note and the look of the rear of the quad
• The stock muffler can be kept and refitted later

Key features

• FMF Factory 4.1 muffler
• Slip-on design that mounts to the stock head pipe
• Bolt-on replacement for the factory muffler
• Listed for the 2013 Yamaha Raptor 700

Best suited to

Riders who want a clear exhaust change on their Raptor 700 with minimal wrenching, and who like the FMF look. Aftermarket mufflers can sound different from stock, so check the rules for the trails and parks you ride.
