• Introducing the brand new Yoshimura R-77 for the GSX-R 1000 !!!

• The trapezoidal shape of the R-77 is all business but as racing enhances the breed – the resultant function driven shape makes for a beautiful muffler

• The R-77 delivers better performance overall because of the larger volume of packing material available due to its design

• Finally, a great sound comes from the R-77 – not loud, but throaty

• The muffler’s front-cap is MIG-welded while the end-cap is riveted using high end 304-L polished stainless steel rivets and bands

• This R-77 Muffler features a straight baffle with a flare style tip and is 14" in length

• The R-77 includes an easily removable Low-Volume Insert (dB Killer)

• The Full System maximizes usable power and torque throughout the entire RPM band, providing optimum gains

• Yoshimura’s Full System exhaust features a 4 into 1 stainless steel header with a single muffler mounted on the right side, minimizing unwanted weight for the performance oriented rider

• This Full System weighs 12.3 Lbs. less than the OEM/stock exhaust system

• This system utilizes the OEM/stock O2/lambda sensor

• This system eliminates the OEM/stock catalytic converter and SET system

• Includes stainless steel headers, Tail-pipe, heat shields and all necessary hardware for easy installation.
