R-55 Muffler

 


The R-55 is currently one of Yoshimura’s most popular pipes, and for good reason. It’s a hybrid of MotoGP, Superbike, and Yoshimura style, which makes for a pretty impressive package. Its asymmetrical shape appeals to the eye and really captures the spirit of MotoGP racing. It also complements the look of any sportbike, following the race-inspired lines of today’s motorcycles.

The R-55 features a straight baffle with removable low-volume insert. The TIG-welded muffler is constructed of high quality 304-L polished stainless steel, and has the option of either a polished 304-L stainless steel or carbon fiber end-cap. The laser cut mounting bracket is TIG-welded to the sleeve for maximum strength and good looks.

The R-55 comes as a Slip-On muffler, which attaches simply to the stock exhaust mounting slip-fit, or on select Yoshimura Full systems.
