The R-77’s trapezoidal shape is serious business when it comes to performance.
This pipe was designed from racetrack feedback from racers Tommy Hayden and Blake Young, so not only does this pipe look great, it does great things for a motorcycle.
The R77 delivers better performance overall because because of the large volume of packing material in it, courtesy of that trapezoidal shape.
The sound coming from this pipe is perfect—not loud, but definitely throaty.
With a straight baffle and removable low-volume insert, the R-77 muffler’s front cap is MIG-welded, while the end cap is riveted using high-end 304-L polished stainless steel rivets and bands.
You can get the muffler either in stainless steel, titanium, or race-inspired carbon fiber.
The cone end caps come in either polished stainless steel or carbon fiber, and the Slip-on itself is mounted with a stainless steel mounting clamp.
You can make this pipe your own with all these choices.
The R-77 comes as a Slip-on muffler, which attaches simply onto the stock exhaust mounting slip-fit, or on various full Yoshimura exhaust systems.
