In place of the resonator, a mandrel-bent X-pipe crossover promotes even flow to both banks of tips and removes the uneven-flow harshness of the stock system. Deleting the resonator adds volume, producing a louder, smoother, fuller exhaust note. Installation is bolt-on using 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;\"\u003eHigh Flow Middle Exhaust (mandrel-bent X-pipe mid-section)\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eDiameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e3in (76mm), replaces 70mm stock\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;\"\u003eD660-0080\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\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\u003e2018-2023\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM550i xDrive\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":46783016566956,"sku":"DNND660-0080","price":1599.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0480\/2160\/2467\/files\/4cb151775e60e7cd3e479014fa96a6acL.jpg?v=1784354847","url":"https:\/\/onefastshop.com\/products\/dinan-3in-high-flow-middle-exhaust-bmw-m550i-xdrive-g30-2018-2023","provider":"OneFastShop","version":"1.0","type":"link"}
