You're in control: XForce Varex muffler kits put the power of sound into your hands. These remote-adjustable mufflers allow you to fine-tune your exhaust notes to match your surroundings—or your mood! With XForce patented technology, the Varex mufflers are engineered with sophisticated butterfly valve mechanisms that redirect exhaust gas flow to alter sound levels. From wide-open flow and robust sound, to chambered flow and more mellow sounds—and everything in-between—you have the freedom to decide what you want, as well as when and where. And, making XForce Varex mufflers even more desirable is their 304 stainless steel construction that's polished to a mirror-like finish. No other muffler offers as much flexibility, combined with performance and style. The choice—and control—is yours! Complete XForce Varex muffler kits include: * Muffler * Harness with water-resistant connector and power plug * Control module * Remote control keypad * Muffler band

FMF Racing's Mini Factory 4.1 slip-on mufflers styling is similar to 4.1 RCT big bike products, with an aggressive look and sound—only lacking the big bike model's internal resonance chamber module. The Factory 4.1 achieves a shorter overall length that is less susceptible to crash damage and complementary to the Factory Forward Engineering, moving mufflers closer to the motor to centralize mass. Visible changes to the exterior include a redesigned canister to increase internal capacity for maximum volume of packing material—which itself is a proprietary blend formulated for superior durability and sound attenuation. The rear endcap has been engineered to provide simple tuning adjustments, incorporating a snap ring feature to secure both the standard and optional inserts. Key features and benefits: * Available in stainless steel or FMFs exclusive Ti-Metal construction * Lightweight—offering huge weight savings * Massive power gains throughout the rpm range * Factory Forward Engineering centralizes mass—improving handling * RTS (Rapid Tuning System) for quick and easy trackside tuning * Tuned exhaust with optimized core specifications for each application * Patented core shape lowers sound level while maintaining maximum power output * Patented canister shape increases internal volume for more sound absorbing material * Quiet insert included (94db) * Removable spark arrestor included on most models * Can be used with FMF or stock OEM header
