Twin 76mm secondary exhaust valves are 45% less restrictive than the OE valves, and the stock valve actuators are reused so exhaust tone still follows the M Drive settings. The valves stay closed to limit noise and drone at low speed and open fully under high load for maximum flow. The system is 3 lbs lighter than stock, adds a claimed 5 hp, and mounts on the factory brackets and hangers.\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;\"\u003eValved axle-back exhaust system (Dinan Free Flow)\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;\"\u003e304 stainless steel\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 3.5 in, laser engraved\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;\"\u003ePolished stainless 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 secondary valves, reuses stock actuators\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e3 lbs lighter than 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\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e+5 hp (Dinan claim)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eD660-0050\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003eDinan warranty matching the factory new car bumper to bumper warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp style=\"margin-top:12px;\"\u003eDocuments: \u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/04f3167cfc1d5814607a75be2e0e3445.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\u003e2015-2018\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2015-2020\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2019-2020\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003eCS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2016\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003eGTS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":47630883553452,"sku":"DNND660-0050","price":2113.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0480\/2160\/2467\/files\/21a594a488b137f632b2683caa8aefc0L.jpg?v=1792125701","url":"https:\/\/onefastshop.com\/products\/dinan-free-flow-polished-tip-axle-back-exhaust-bmw-m3-f80-m4-f82-f83-2015-2020","provider":"OneFastShop","version":"1.0","type":"link"}
