The Yoshimura R-77 Race Series is a dual muffler slip-on exhaust system engineered for high performance, stemming from its development in competitive racing environments. This system features a distinctive trapezoidal-shaped sleeve, which maximizes packing material volume to achieve peak performance. The muffler's construction involves a MIG-welded front cap and an end cap secured with premium 304-L polished stainless steel rivets and bands. Key features of this exhaust include its dual muffler configuration, superbike technology and styling, and a straight baffle design that ensures ample flow. The slip-on system is crafted with stainless steel tailpipes, contributing to both durability and aesthetics. It is important to note that this product is designated as a "RACE SERIES" by Yoshimura and is intended exclusively for closed-course competition use. It is neither designed nor intended for use on public roads or land, and such use is prohibited by federal and state regulations. This product was designed and tested to fit on standard, factory-equipped motorcycles. Compatibility with OE or aftermarket accessories not originally delivered with the vehicle may vary. Attention international customers should be aware that this product's compatibility, including fitment and performance, is based on vehicles in the U.S. marketplace only and may differ in other regions.
