The Yoshimura YZF-R1 09-14 R-77 Stainless Slip-On Exhaust is engineered for outstanding performance, stemming from its development in competitive racing environments. This slip-on system features a distinctive trapezoidal muffler design, which maximizes the volume of packing material for enhanced performance. The system includes a straight baffle for optimal flow and a removable low-volume insert, offering versatility. It also utilizes a stainless steel tail-pipe and is 1.1 lbs lighter than the stock configuration, contributing to improved agility. This dual under-tail configuration integrates superbike technology and styling, aiming to elevate both the aesthetics and performance of your Yamaha YZF-R1. The slip-on design facilitates a straightforward installation process compared to full exhaust systems, while still offering significant performance gains and a distinct Yoshimura sound.
