It weighs 10 lbs less than the stock BMW assembly and adds 6 hp and 5 lb-ft at 6,800 rpm, while an internal Helmholtz chamber cancels the cruising drone typical of free flowing systems. The system exits through quad 3 in black ceramic coated, laser engraved tips and hangs from the factory brackets and hangers for a stock-like fit.\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;\"\u003eAxle-back exhaust system, single channel straight through with Helmholtz chamber (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;\"\u003e100% T304 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\u003eFinish\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eBlack ceramic coated, laser engraved tips\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eSize\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eQuad 3 in tips\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eOutput\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e+6 hp and +5 lb-ft at 6,800 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;\"\u003eD660-0028\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp style=\"margin-top:12px;\"\u003eDocuments: \u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/18c4e5e1fe3328594b2cc6302886666e.PDF\"\u003eInstallation Instructions (PDF)\u003c\/a\u003e  |  \u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/706c6bafd0bd26c0c00b1713d9d62817.PDF\"\u003eWhitepaper (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\u003e2008-2011\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\u003c\/table\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":46957174292652,"sku":"DNND660-0028","price":2349.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0480\/2160\/2467\/files\/18958561af80f1fe99844f8504600f54L.jpg?v=1787103078","url":"https:\/\/onefastshop.com\/products\/dinan-free-flow-axle-back-exhaust-bmw-m3-e90-2008-2011-black-tips","provider":"OneFastShop","version":"1.0","type":"link"}
