F3805 and the old product number: DL30-6410 are the same product. A silencer that has achieved increased power output across the entire RPM range by improving exhaust efficiency and balancing exhaust pressure. The silencer, which has a thoroughly refined internal structure, is combined with a multi-stage expansion mid-pipe to achieve a balance between exhaust efficiency at high RPM and torque at low and mid RPM. The mid-pipe is made of corrosion-resistant stainless steel, and the silencer body is made of aluminum, making it significantly lighter than the original muffler. Furthermore, by placing the silencer body closer to the center of gravity of the vehicle, it contributes to improving power performance. It was developed for use in a variety of genres, including enduro and motard racing. Close-range exhaust noise: 94db or less (restrictor fitted as standard).
