2011 Kawasaki ZX-10R: Yoshimura R-77

2011 Ninja Exhaust

Yoshimura R&D of America has announced a host of applications for R-77 and all-new R-77D to outfit the 2011 Kawasaki ZX-10R. Slip-ons and full systems will be available in a number of configurations.

The R-77 is serious business when it comes to performance as it was designed with racetrack feedback from AMA Superbike racers Tommy Hayden and Blake Young.

The R-77’s trapezoidal shape allows a large volume of packing material and in turn delivers top performance. 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 in stainless steel, titanium, or race-inspired carbon fiber.

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. 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.

Introducing the all-new R-77D. A dual-outlet version of the race-proven R-77, the R-77D boasts a carbon fiber cone end cap and polished stainless steel dual outlet turndown.

The R-77D requires no inserts or restrictions, increasing muffler packing life, and provides 5-percent more open exhaust outlet area and as much as 3 decibels lower sound output (compared to open standard R77). The R-77D also offers greater gains in bottom and mid range power with out restrictive inserts. The R-77D was born from the popular trapezoidal shaped R-77.
