Superbike styling right from Yoshimura Factory Road Racing! The trapezoidal shape is all business but as racing enhances the breed – the result 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 R-77 features a straight baffle with removable low volume insert. 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.
Slip-On includes R-77 muffler, stainless steel tail-pipe, installation hardware, and detail step-by-step instructions.

IF you own a can-am spyder RS model,& want a really great sound. this is the exhaust to purchase.Wehave the two brothers daul exhaust also. Would not work with stock side saddles.thought they werethe best out .but after testing 4 others,we found the yoshimura R -77 slip on was by far superior tothem all in every way.many compliments everywhere we have been.half the cost of most other exhaust isa big plus. The help & fast delivery from competition accessories only added to our delight. Ifu want to complete your spyder look & sound.this is the way to go.
