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\u003cbr\u003e\nDesigned To Fit:\u003cbr\u003e\n2018 Yamaha YZ450F\u003cbr\u003e\n2018 Yamaha YZ450FX\u003cbr\u003e\n2019 Yamaha WR450F\u003cbr\u003e\n2019 Yamaha YZ450F\u003cbr\u003e\n2019 Yamaha YZ450FX\u003cbr\u003e\n2020 Yamaha WR450F\u003cbr\u003e\n2020 Yamaha YZ450F\u003cbr\u003e\n2020 Yamaha YZ450FX\u003cbr\u003e\n2021 Yamaha WR450F\u003cbr\u003e\n2021 Yamaha YZ450F\u003cbr\u003e\n2021 Yamaha YZ450F Monster Energy Yamaha Racing Edition\u003cbr\u003e\n2021 Yamaha YZ450FX\u003cbr\u003e\n2022 Yamaha WR450F\u003cbr\u003e\n2022 Yamaha YZ450F\u003cbr\u003e\n2022 Yamaha YZ450F Monster Energy Yamaha Racing Edition\u003cbr\u003e\n2022 Yamaha YZ450FX\u003cbr\u003e\n2023 Yamaha WR450F\u003cbr\u003e\n2023 Yamaha YZ450F\u003cbr\u003e\n2023 Yamaha YZ450F Monster Energy Yamaha Racing Edition\u003cbr\u003e\n2023 Yamaha YZ450FX\u003cbr\u003e\n2024 Yamaha WR450F\u003cbr\u003e\n2024 Yamaha YZ450F\u003cbr\u003e\n2024 Yamaha YZ450F 50th Anniversary Edition\u003cbr\u003e\n2024 Yamaha YZ450FX\u003cbr\u003e\n2025 Yamaha WR450F\u003cbr\u003e\n2025 Yamaha YZ450F\u003cbr\u003e\n2025 Yamaha YZ450F Monster Energy Yamaha Racing Edition\u003cbr\u003e\n2025 Yamaha YZ450FX","brand":"FMF Racing","offers":[{"title":"Default Title","offer_id":53405602316601,"sku":"fmf044442","price":449.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/6656\/6201\/files\/178c55cabfd458bde7afdb6f89cebd0c.jpg?v=1781332003","url":"https:\/\/ridenowparts.com\/products\/fmf-racing-yamaha-yz450f-18-26-wr450f-2019-yz450fx-19-24-hex-q4-s-a-muffler","provider":"RideNow Parts","version":"1.0","type":"link"}
