2015-2021 Yamaha R3/MT-03 stainless steel full system with polished canister.
M4 has gone to great lengths to make sure the pipe for the R3 is better than the competition. We are confident this system will give you the most power possible from any aftermarket pipes available. Comes with a “race bracket” or you can still use the passenger foot peg assembly. Produces 10% more horsepower than the stock system and weighs 10.5 lbs less.
Does not meet emission requirements for street or highway use.
