Product Description

The MBRP AT-7401 Utility Series Slip-On Exhaust is engineered as a direct replacement for the stock muffler on select Yamaha ATVs, including the Moto-4 and Tri-Moto 225 models. Constructed from black-coated aluminized steel, this exhaust system offers enhanced durability and corrosion resistance. Its chambered internal design ensures a consistent and slightly more aggressive sound compared to the OEM muffler, while also improving exhaust flow for better performance.

Installation is straightforward with a bolt-on design that requires no additional tuning. The included USFS-approved spark arrestor makes it suitable for trail use, meeting necessary compliance standards. Backed by a 1-year warranty, the MBRP AT-7401 provides a reliable and efficient upgrade for your ATV's exhaust system.
