Monster introduces the front pipe which uses high quality stainless steel SUS304. Decreasing loss vis-a-vis the front pipe whose bending is many with tandem of standard equipment, with the straight pipe of large diameter. The especially inside, occurrence torque in the high rotary limits was increased considerably. Vis-a-vis the press formation flange, adopting the 9t flange. By the fact that rigidity and heat mass are guaranteed, seal characteristic at the time of high load continual driving such as circuit travelling it improved.
