Show original supplier description
The Yoshimura Street Dual R-77 Slip-On Exhaust brings superbike styling directly from Yoshimura's top-tier racebikes to your machine. This system features a straight baffle design and includes a removable low-volume insert, allowing you to tune the exhaust note to your preference. The muffler's front cap is MIG-welded, and the end cap is secured with high-end 304-L polished stainless steel rivets and bands, ensuring durability and a premium finish. The R-77 system is designed to mount to the OEM header with ease, offering a significant weight savings of 3-10 lbs over the stock muffler and an average horsepower gain of 5 HP. The midpipe is crafted from 304-L polished stainless steel, providing the aesthetic of a full system. It is equipped with carbon fiber sleeves and carbon fiber tips, contributing to its performance-oriented look and lighter weight. This Yoshimura R-77 Dual Slip-On Exhaust is specifically designed for the Suzuki GSX1300R Hayabusa models from 2008 to 2020, including the 2012 GSX1300RZ Limited Edition. Please note that this exhaust system is not CARB Approved and will not ship to California. Additionally, some sources indicate it may not be intended for road use, though it offers performance style and value.
