HKS increased the main pipe size from 80mm to 85mm, extracting an extra measure of power from the B58 inline-six. The system retains the factory valved exhaust setup and reuses the OEM actuator motor, so you control the sound just like the factory system.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMain pipe increased from 80mm to 85mm, sized to support subsequent upgrades\u003c\/li\u003e\n\u003cli\u003eRetains full factory valve operation using the OEM actuator and control — no additional controller needed\u003c\/li\u003e\n\u003cli\u003eFull independent dual layout for both banks — no 2-into-1 junction like the stock system\u003c\/li\u003e\n\u003cli\u003eReduces exhaust interference, enabling stress-free revving through the high-RPM range\u003c\/li\u003e\n\u003cli\u003eExhaust note tuned through extensive sound-frequency analysis for a distinct, pleasant tone\u003c\/li\u003e\n\u003cli\u003eDyno-proven gains of 30+ horsepower, verified internally at HKS and by external facilities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHKS dual-muffler cat-back exhaust system\u003c\/li\u003e\n\u003cli\u003eGaskets and mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eReuses the stock exhaust valve actuator and control — no additional controller required\u003c\/li\u003e\n\u003cli\u003eFor vehicles without OPF (Otto Particulate Filter)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e31014-KT001\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eToyota\u003c\/td\u003e\n\u003ctd\u003eGR Supra 3.0 (without OPF)\u003c\/td\u003e\n\u003ctd\u003eA90\/A91\u003c\/td\u003e\n\u003ctd\u003eB58\u003c\/td\u003e\n\u003ctd\u003e2020–2026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":53630965285171,"sku":"31014-KT001","price":3050.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/4226\/2579\/files\/31014-KT001-hks-exhaust-2020-supra-a90-gr-1.jpg?v=1785890114","url":"https:\/\/x58cartel.com\/products\/hks-dual-muffler-exhaust-system-toyota-gr-supra-a90-a91","provider":"x58cartel","version":"1.0","type":"link"}
