Repacking at those intervals helps prevent dirty packing from restricting airflow, which can lead to lost power and degraded sound. This kit includes the components needed to repack dual RS-9T mufflers and bring back freer airflow and improved exhaust tone.\u003c\/p\u003e\n\u003cul class=\"trd-chips\"\u003e\n\u003cli class=\"trd-chip\"\u003e\n\u003cspan class=\"trd-chip-label\"\u003ePart Number\u003c\/span\u003e\u003cspan class=\"trd-chip-value\"\u003eREPACK-RS9T-P13\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"trd-chip\"\u003e\n\u003cspan class=\"trd-chip-label\"\u003eSeries\u003c\/span\u003e\u003cspan class=\"trd-chip-value\"\u003eRS-9T\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"trd-chip\"\u003e\n\u003cspan class=\"trd-chip-label\"\u003eFits\u003c\/span\u003e\u003cspan class=\"trd-chip-value\"\u003eHonda CRF250R \/ CRF250RX\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/section\u003e\u003cdiv class=\"trd-cards trd-cards--3\"\u003e\n\u003carticle class=\"trd-card\"\u003e\u003cdiv class=\"trd-card-body\"\u003e\n\u003ch3 class=\"trd-card-title\"\u003eDual muffler kit\u003c\/h3\u003e\n\u003cp class=\"trd-card-text\"\u003eBuilt specifically to service dual RS-9T mufflers, this repack kit is supplied with the parts required to complete the job on both sides.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/article\u003e\u003carticle class=\"trd-card\"\u003e\u003cdiv class=\"trd-card-body\"\u003e\n\u003ch3 class=\"trd-card-title\"\u003ePremium packing material\u003c\/h3\u003e\n\u003cp class=\"trd-card-text\"\u003eThe kit includes Silent Sport Premium Packing Material in 550g x 2 QTY.

Over time, dirty packing can restrict airflow from the motor, which results in a loss of power and degradation of sound. By replacing the packing at the suggested intervals, airflow is restored for freer breathing and the exhaust note is improved, helping keep the system consistent through repeated hours of use and race conditions.\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\"\u003eMaterials\u003c\/p\u003e\n\u003ch3 class=\"trd-story-title\"\u003eWhat’s included in the kit\u003c\/h3\u003e\n\u003cp class=\"trd-story-text\"\u003eThis RS-9T Dual Premium Muffler Repack Kit is assembled as a complete service solution for dual mufflers, combining packing material with key hardware and finishing items.
