A vacuum controlled butterfly valve is utilized to improve flow at wide-open throttle while keeping things civilized and \"drone\" free throughout. The design reduces overall weight as well and features 3.5'' polished, or ceramic black, tips for a tasteful high-performance look.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMore Power: + 10 HP when coupled with engine software\u003c\/li\u003e\n\u003cli\u003eDrone abatement technologies used to reduce cabin resonance\u003c\/li\u003e\n\u003cli\u003eEnjoyably louder, sportier sound\u003c\/li\u003e\n\u003cli\u003eQuad 3.5\" laser engraved, polished or ceramic black exhaust tips\u003c\/li\u003e\n\u003cli\u003e100% 304 stainless steel construction\u003c\/li\u003e\n\u003cli\u003eUses the factory brackets and hangers for a factory-like fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e T304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Dinan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Exhaust\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamps Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDinan Point Value:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmission Code:\u003c\/strong\u003e 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExhaust Tip Quantity:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Brushed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHangers Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLabor Time (Hours):\u003c\/strong\u003e 1.6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e T304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax HP Gain:\u003c\/strong\u003e 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Material:\u003c\/strong\u003e T304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Axle-Back Exhaust\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Category:\u003c\/strong\u003e Exhaust and Tail Pipes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Finish:\u003c\/strong\u003e Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 78\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 29\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":44849820467335,"sku":"DIND660-0036","price":3487.33,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/22e3253bdab50ae6a6cf10648f3a344f.jpg?v=1788268348","url":"https:\/\/checkout.northernperformance.ca\/products\/dinan-free-flow-axle-back-exhaust-2011-2016-bmw-550i","provider":"Northern Performance","version":"1.0","type":"link"}
