It exits through quad 4.5in (114mm) double-walled, black ceramic-coated, laser-engraved tips that use an inverted clamp-neck design to hide the clamp and keep a clean, straight-cut face. Dinan rates gains of +8 HP and +6 lb-ft at 6600 RPM, and the system is about 5 lbs lighter than stock. Installation is bolt-on with the included mounting hardware.\u003c\/p\u003e\n\u003ch2 style=\"margin:16px 0 4px 0;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"border-collapse:collapse;width:100%;margin-top:0;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eFree Flow axle-back exhaust (dual-valve)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eT304 stainless steel, TIG welded, brushed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eTips\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eQuad 4.5in (114mm) double-walled, laser-engraved, inverted clamp-neck\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eFinish\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eBlack ceramic-coated tips\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eValves\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eTwin 76mm computer-controlled (30% less restrictive than OE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003ePiping Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e76mm (vs 70mm stock)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003ePower Gain\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e+8 HP \u0026amp; +6 lb-ft @ 6600 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003eD660-0086-BLK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp style=\"margin-top:12px;\"\u003eDocuments: \u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/31866f50c72f1665dc6e112acd426a9c.PDF\"\u003eInstallation Instructions (PDF)\u003c\/a\u003e\u003c\/p\u003e\n\u003cp style=\"margin-top:12px;\"\u003eThis part fits:\u003c\/p\u003e\n\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2020-2024\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eX3\u003c\/td\u003e\n\u003ctd\u003eM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2020-2022\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eX3\u003c\/td\u003e\n\u003ctd\u003eM Competition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2020-2025\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eX4\u003c\/td\u003e\n\u003ctd\u003eM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2020-2022\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eX4\u003c\/td\u003e\n\u003ctd\u003eM Competition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":46783016763564,"sku":"DNND660-0086-BLK","price":2699.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0480\/2160\/2467\/files\/06a14295bfb923456da128211c980991L.jpg?v=1784354849","url":"https:\/\/onefastshop.com\/products\/dinan-free-flow-axle-back-exhaust-bmw-x3-m-x4-m-f97-f98-2020-2025-black-tips","provider":"OneFastShop","version":"1.0","type":"link"}
