The popular R-77 Full System offers outstanding performance, thanks to being developed in the heat of competition.
It features a trapezoidal design, which allows a large volume of packing material and in turn delivers top performance. 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.
-m-2017 YAMAHA FZ-07 (ABS)-- Great exhaust would definitely recommend for somebody who wants an upgrade. Easy installation took me about 30 minutes to install. Small bit of backfire when downshifting to slow down but other than that great exhaust.
Great purchase. Looks good, sounds great. A tiny bit of weld slag on pipes at 3-1 junction. Can't say yet on durability but hoping for the best. I think Yoshi is a top line product. Rocky Mtn is great.
New Yoshi and ECU flash have made this a BEAST. Rocky Mountain is a great place to shop
