Utilizing factory cut points and mounting mechanics, this is a straightforward, precision-fit install — but that's where the similarities to the factory exhaust end. Fabricated from brushed 100% T304 stainless steel, TIG welded, and free of hydroformed pipe, the Dinan system abandons the stock single-to-dual pipe layout for an enlarged, free-flowing single pipe design that feeds a drone-abating muffler tuned for the signature deep, rich Dinan tone. Gases exit through massive dual 4.5\" straight-cut tips laser engraved with the Dinan logo. Factory valve control is fully retained, so you can keep it civil for early mornings or open it up for a full-throttle symphony — sound without sacrifice, in one refined package.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUp to +6 HP and +5 lb-ft torque gains\u003c\/li\u003e\n\u003cli\u003eLarger diameter piping throughout (83mm primary run vs. 80mm stock at largest point)\u003c\/li\u003e\n\u003cli\u003eFactory resonator\/collector removed for increased volume and flow\u003c\/li\u003e\n\u003cli\u003e10 lbs lighter than stock (Stock: 56 lbs vs. Dinan: 46 lbs)\u003c\/li\u003e\n\u003cli\u003e100% T304 stainless steel, TIG welded, brushed finish, free of hydroformed pipe\u003c\/li\u003e\n\u003cli\u003eDual 4.5\" (114.3mm) double-walled, polished clamp-on tips with laser-engraved Dinan logo\u003c\/li\u003e\n\u003cli\u003eRetains factory exhaust valve control — full sound adjustability, from tame to full-throttle\u003c\/li\u003e\n\u003cli\u003eDrone-abating muffler design for a civil daily-drivable tone\u003c\/li\u003e\n\u003cli\u003eLegal for sale or use on Emissions Controlled, Non-Emissions Controlled, and Racing Use Only vehicles (does not affect emissions)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x valved cat-back exhaust (Polished or Black Ceramic Coated tips per variant)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0961\/4226\/2579\/files\/d660-0096-blk.pdf?v=1785452305\" rel=\"noopener\" target=\"_blank\"\u003eInstallation Instructions (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eRecommended pairing: Dinan \u003ca href=\"https:\/\/x58cartel.com\/products\/dinan-gloss-carbon-fiber-cold-air-intake-gr-supra-and-z4\"\u003eCarbon Fiber Cold Air Intake (D760-0065)\u003c\/a\u003e and \u003ca href=\"https:\/\/x58cartel.com\/products\/dinan-carbon-fiber-turbo-inlet-pipe-b58-engine\"\u003eTurbo Inlet (D760-0062)\u003c\/a\u003e — as featured in the A9x GR Supra Foundation Package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePolished Stainless Steel Tips — D660-0096\u003c\/li\u003e\n\u003cli\u003eBlack Ceramic Coated — D660-0096-BLK\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\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\u003eYears\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eToyota\u003c\/td\u003e\n\u003ctd\u003eGR Supra 3.0\u003c\/td\u003e\n\u003ctd\u003eA90 \/ A91\u003c\/td\u003e\n\u003ctd\u003eB58 3.0L\u003c\/td\u003e\n\u003ctd\u003e2020–2026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003ePlease confirm exact fitment for your VIN before purchase.\u003c\/em\u003e\u003c\/p\u003e","brand":"Dinan","offers":[{"title":"Black Ceramic Coated","offer_id":53596121661747,"sku":"D660-0096-BLK","price":1749.95,"currency_code":"USD","in_stock":true},{"title":"Polished","offer_id":53596121628979,"sku":"D660-0096","price":1749.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/4226\/2579\/files\/a226214b6177ab117fc6f1e11b8d54d28d68f69d.jpg?v=1782946373","url":"https:\/\/x58cartel.com\/products\/dinan-valved-cat-back-exhaust-toyota-supra-a90-a91","provider":"x58cartel","version":"1.0","type":"link"}
