The R-77's trapezoidal shape allows a large volume of packing material and in turn delivers a nice tuned sound. The R-77 muffler's inlet cap is MIG-welded, while the end cap is riveted using high-end 304L polished stainless steel rivets and bands.
Slip-on systems include the R-77 muffler, stainless steel mid-pipe, and all necessary hardware for installation.
