With the latest engine spec, our engineers wanted to get the best most usable power from this new model. This new system incorporates a one-piece stainless steel cast manifold featuring an integrated bolt flange surface that is 3x stronger than conventional designs.\u003c\/p\u003e\n\u003cp\u003eThis new system has been developed with - and is the closest thing to what 5x World Champion Tim Gajser, Chase Sexton, Jett Lawrence have been using to grab holeshots and win championships. By increasing the resonator in the RS-12 muffler by 50cc (a 14% increase) and adding a second resonator to the header, our engineers were able to unlock some insane usable power from this new and improved system.\u003c\/p\u003e\n\u003cp\u003eThe new RS-12 system adds 5% max hp and 6.5% max torque to the new engine spec with its smaller throttle body and different ECU settings.\u003c\/p\u003e\n\u003cp\u003eWhat does this translate to?\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEasier power delivery\u003c\/li\u003e\n\u003cli\u003eSmoother frontside torque\u003c\/li\u003e\n\u003cli\u003eAllows the rider to ride in an higher gear, thus freeing up suspension.\u003c\/li\u003e\n\u003cli\u003eLess rider fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eYoshimura's RS-12 is proudly designed, developed and manufactured in Chino, California.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/LkWSdyrUhRM\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e'\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;
