If their full race system goes beyond your needs, Yoshimura's RS-12 Enduro Series Slip-On Exhaust is the ideal solution. With the included USFS-approved spark arrestor installed, this system boosts horsepower by 4.1% at 8,000 RPM and increases torque by 2% at 4,800 RPM—all while staying legal for street use. This exhaust also reduces component weight by 4.4 lbs when compared to the stock exhaust, and features Yoshimura's distinct canister design and carbon fiber exhaust cap.\u003c\/p\u003e\r\n\r\n\u003cp\u003ePerformance figures stated are reported with the USFS spark arrestor SA-21-K installed.\u003c\/p\u003e\r\n\r\n\u003cdiv class=\"tst-table gray\"\u003e\r\n\u003ctable class=\"tst-tb newTable\"\u003e\r\n\u003ctbody\u003e\r\n\u003ctr class=\"tst-tr\"\u003e\r\n\u003ctd class=\"tst-td\"\u003e\u003cstrong\u003eSystem Configuration\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\"\u003e\u003cstrong\u003eSound Level (2000 RPM)\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\"\u003e\u003cstrong\u003eSound Level (5000 RPM)\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr class=\"tst-tr\"\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"System Configuration\"\u003eYoshimura RS-12 Slip-On\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Sound Level (2000 RPM)\"\u003e86.0 dB\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Sound Level (5000 RPM)\"\u003e89.3 dB\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Weight\"\u003e9.2 lbs\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\r\n\u003ctr class=\"tst-tr\"\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"System Configuration\"\u003eStock system\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Sound Level (2000 RPM)\"\u003e74.4 dB\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Sound Level (5000 RPM)\"\u003e84.4 dB\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Weight\"\u003e13.6 lbs\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\r\n\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\u003c\/div\u003e\r\n\u003cp\u003e\u003cem\u003eSound levels measured using SAE J2825 standard with installed spark arrestor.\u003c\/em\u003e\u003c\/p\u003e \r\n\r\n\r\n\u003cem\u003e\u003cspan style=\"color: #f00;\"\u003eEmissions Compliance Declaration:\u003c\/span\u003e Qualified manufacturer declared \"replacement part\".\u003c\/em\u003e","brand":"Yoshimura","offers":[{"title":"Default Title","offer_id":48288681263336,"sku":"YOSH-1042","price":789.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/9340\/9000\/files\/Yoshimura-Enduro-RS-12-Slip-On-Exhaust-for-Suzuki-DR-Z4S-and-DR-Z4SM-2025__Thumbnail-1_9b36ba25-7ba3-4874-8c67-aeb3aa8bb5b4.jpg?v=1776765179","url":"https:\/\/tstindustries.com\/products\/yoshimura-enduro-rs-12-stainless-slilp-on-exhaust-suzuki-dr-z4s-dr-z4sm-2025","provider":"TST Industries, LLC.","version":"1.0","type":"link"}
