The surface of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up at higher air pressures (RPMs). The Power Bomb is a \"pre-muffler\" of sorts, which helps to lower the bike's sound output because it provides more sound-absorbing surface area to allow the exhaust gases to become absorbed.\u003c\/p\u003e\n\n\u003cp\u003eFitment:\n\u003cbr\u003eHonda CRF450R Base 2021\n\u003cbr\u003eHonda CRF450R Base 2022\n\u003cbr\u003eHonda CRF450R Base 2023\n\u003cbr\u003eHonda CRF450RX Base 2021\n\u003cbr\u003eHonda CRF450RX Base 2022\n\u003cbr\u003eHonda CRF450RX Base 2023\u003c\/p\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbdoy\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Unknown\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: powersports\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: Compliant\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: t\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbdoy\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"FMF Racing","offers":[{"title":"Default Title","offer_id":46148500881561,"sku":"fmf041601","price":373.74,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/2611\/3689\/files\/178c55cabfd458bde7afdb6f89cebd0c.jpg?v=1770698469","url":"https:\/\/msvracingpowersports.com\/products\/fmf-racing-honda-crf450r-rx-21-24-q4-s-a-muffler","provider":"MSV Racing","version":"1.0","type":"link"}
