Engineered and manufactured in Chino, California, this slip-on system replaces the heavy, restrictive factory muffler with a high-flowing stainless steel unit capped with lightweight matte carbon fiber.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eBy increasing exhaust flow, the RS-12 slip-on delivers immediate and noticeable power gains, providing up to a 7.0% increase in horsepower and a 7.5% boost in torque at 5,000 RPM. This extra mid-range punch is exactly where the CRF300L needs it most for tackling steep inclines or passing on the highway. Beyond power, this system shaves 2.7 pounds off the rear of the motorcycle, noticeably improving the bike's center of gravity and suspension response. It includes a USFS-approved spark arrestor, ensuring your bike remains fully compliant for legal trail riding on public lands.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"3\"\u003eFeatures:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003eProven Power Gains:\u003c\/b\u003e Unlocks up to 7.0% more horsepower and 7.5% more torque at 5,000 RPM for immediate mid-range acceleration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,1,0\"\u003e\u003cb data-path-to-node=\"4,1,0\" data-index-in-node=\"0\"\u003eWeight Reduction:\u003c\/b\u003e Weighs only 7.3 lbs compared to the 10.0 lb stock muffler, improving off-road handling and chassis balance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,2,0\"\u003e\u003cb data-path-to-node=\"4,2,0\" data-index-in-node=\"0\"\u003ePremium Construction:\u003c\/b\u003e Features a stainless steel muffler body and mid-pipe for rugged off-road durability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,3,0\"\u003e\u003cb data-path-to-node=\"4,3,0\" data-index-in-node=\"0\"\u003eCarbon Fiber Details:\u003c\/b\u003e Finished with a distinctive matte carbon fiber end cap and includes a matching custom matte carbon fiber heat shield.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,4,0\"\u003e\u003cb data-path-to-node=\"4,4,0\" data-index-in-node=\"0\"\u003eTrail Legal:\u003c\/b\u003e Comes standard with a pre-installed USFS-approved spark arrestor screen.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,5,0\"\u003e\u003cb data-path-to-node=\"4,5,0\" data-index-in-node=\"0\"\u003eMade in the USA:\u003c\/b\u003e Designed, developed, and manufactured in Yoshimura's Chino, California facility.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 data-path-to-node=\"5\"\u003eWhat's in the Box:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e1x Yoshimura RS-12 Stainless Steel Muffler\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e1x Stainless Steel Slip-On Mid-Pipe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e1x Matte Carbon Fiber Heat Shield\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e1x USFS Approved Spark Arrestor - Installed\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,4,0\"\u003eComplete Mounting Hardware Kit\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,5,0\"\u003eInstallation Instructions\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch4\u003e2021–2026 – Honda CRF300L\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e2021–2026 – Honda CRF300L Rally\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 data-path-to-node=\"7\"\u003eFitment Notes:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"8\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,2,0\"\u003e\u003cb data-path-to-node=\"8,2,0\" data-index-in-node=\"0\"\u003eHeader Compatibility:\u003c\/b\u003e Designed to mate seamlessly with the OEM Honda header pipe.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cp data-path-to-node=\"12\"\u003e\u003cb data-path-to-node=\"12\" data-index-in-node=\"0\"\u003eThe Mid-Range Wake Up:\u003c\/b\u003e The CRF300L is a fantastic dual-sport, but its factory power delivery can feel incredibly flat right in the middle of the RPM range. The RS-12 slip-on targets this exact dead zone. By generating over a 7% increase in torque at 5,000 RPM, the bike will feel significantly more urgent when you roll on the throttle in second and third gear. This makes popping the front wheel over logs or accelerating out of deep sand much more predictable.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13\"\u003e\u003cb data-path-to-node=\"13\" data-index-in-node=\"0\"\u003eRepacking is Maintenance:\u003c\/b\u003e Unlike the factory baffled muffler, the RS-12 is a straight-through mechanical core wrapped in fiberglass packing material. Over time, extreme exhaust heat and pressure will burn this packing out, leading to a much louder exhaust note and a potential loss of power. For optimal performance, Yoshimura recommends repacking the muffler with their premium MX repack kit (REPACK-RS12-MX) every 6 to 8 hours of hard race use, or once a season for typical dual-sport trail riding.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0622\/5720\/1317\/files\/Made_In_The_USA_24865b83-5069-42c1-b4bc-9e28ee4fe2cb.jpg?v=1719961954\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003ePart Number: 123412S520\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Yoshimura","offers":[{"title":"Default Title","offer_id":50587626373285,"sku":"YOSH-RS-12-SLIP-CRF-300","price":749.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0622\/5720\/1317\/files\/YoshimuraRS-12Slip-OnExhaustCRF300LSide123412S520.jpg?v=1791302923","url":"https:\/\/www.tmbrmoto.com\/products\/yoshimura-rs-12-slip-on-exhaust-honda-crf300l-crf300l-rally","provider":"TMBR MOTO","version":"1.0","type":"link"}
