高出力と高浄化性能という相反する関係を高い次元で両立
High Flow Efficiency and Exhaust Purification, two opposite characteristic brought to the limit.

- 触媒自体の高効率化だけでなくタービンアウトレット部分の高効率化により排圧低減効果が得られ、過給圧の立ち上がりが鋭くなり高回転域まで気持ちの良いフィーリングが得られます。
The exhaust pressure is reduced not only by improving the efficiency of the catalyzer but also with a more efficient structure that does not load the turbine outlet. As a result, the acceleration filling becomes more smooth on a complete RPM range. - あわせて耐ノック性の余裕が生まれ安全マージンの確保ができチューニングの発展性が広がります。
By reducing exhaust pressure, engine knocking can be suppressed, and the engine able to support more aggresive tuning.
