As packing becomes dirty, Yoshimura states it can restrict airflow from the motor, contributing to a loss of power and a decline in sound quality. A fresh repack helps return the muffler to freer airflow and improved sound, keeping the exhaust closer to its designed operating condition.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e\u003csection class=\"trd-story trd-story--text\"\u003e\u003cdiv class=\"trd-story-copy\"\u003e\n\u003cp class=\"trd-label\"\u003eEngineering\u003c\/p\u003e\n\u003ch3 class=\"trd-story-title\"\u003eDesigned for Dual RS-9T\u003c\/h3\u003e\n\u003cp class=\"trd-story-text\"\u003eThis premium repack kit is engineered specifically for the dual RS-9T mufflers fitted to Honda CRF450RWE (Works Edition) bikes.
