The RS-4 is one of Yoshimura's most proven designs. Its pentagonal-shaped muffler maximizes internal volume, and the polyresonant duplex front chamber with a stepped, two-stage core baffle delivers strong, usable power while managing sound.\u003c\/p\u003e\n\u003cp\u003eThis slip-on features a aluminum canister with a carbon fiber end cap, built to the same standards as Yoshimura's factory race exhausts. Yoshimura builds exhaust systems for factory race efforts, and the knowledge they gain on the track goes straight into their consumer products. That cycle of development is what makes the Yoshimura name synonymous with quality and performance, delivering more power, lower sound levels and better mass centralization. Every Yoshimura system is designed and dyno tested for the specific model it fits, so you get real gains you can feel, not just more noise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e✓ Fits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2019-2023 Yamaha YZ250F\u003c\/li\u003e\n\u003cli\u003e2020-2023 Yamaha YZ250FX\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e✓ Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePentagonal-shaped muffler\u003c\/li\u003e\n\u003cli\u003eMaximized internal volume\u003c\/li\u003e\n\u003cli\u003ePolyresonant duplex front chamber\u003c\/li\u003e\n\u003cli\u003eStepped, two-stage core baffle\u003c\/li\u003e\n\u003cli\u003eSpark arrestor and sound insert compatible\u003c\/li\u003e\n\u003cli\u003eBolt-on fit for the listed models\u003c\/li\u003e\n\u003cli\u003eFor closed-course competition use only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e✓ What's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Yoshimura RS-4 Slip-On\u003c\/li\u003e\n\u003cli\u003eSpark arrestor sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eShips fast from DuneGoonShop!\u003c\/strong\u003e\u003c\/p\u003e","brand":"WPS","offers":[{"title":"Default Title","offer_id":51132259893473,"sku":"961-6415","price":937.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1219\/2993\/files\/2bcf-5cc73223ea618.jpg?v=1792715200","url":"https:\/\/dunegoonshop.com\/en-ca\/products\/yoshimura-rs-4-slip-on-yamaha-yz250f-yz250fx-2019-2023","provider":"Dune Goons","version":"1.0","type":"link"}
