The magic of the right tube diameter, right length then our RS-12 was called in to do the work that it was designed to do...perform! Adding power and torque everywhere across the spectrum of the new YZ450 wasn't easy but it was accomplished. Max HP is increased by 8% and max torque is bumped an incredible 13%!\u003c\/p\u003e\n\u003cp\u003eThe new RS-12 system unlocked some key power in the right places. The lower and mid RPM range is really enhanced while not disrupting the handling characteristics on the new YZ chassis. Riding with this new added power really made testing the new system a fun project.\u003c\/p\u003e\n\u003cp\u003eOther highlights of the RS-12 system are the machined joints on the key tube junctions to insure a good clean interface between joints. A built in resonator chamber on the muffler, a matte carbon fiber end cap and a PTF low volume sound insert completes the RS-12.\u003c\/p\u003e\n\u003cp\u003eSpark arrestor sold separately.\u003c\/p\u003e\n\u003cp\u003eThe RS-12 proudly designed, developed and made in the USA.\u003c\/p\u003e\n\u003ch6\u003eSound Insert\/Spark Arrester Options                 \u003c\/h6\u003e\n\u003cdiv style=\"text-align: center;\"\u003e​​\u003c\/div\u003e\n\u003ctable style=\"border: 1px #000000;
