Not only is the tone improved but the additional burbles and pops that come with it are simply intoxicating. Dinan also incorporates a Helmholtz chamber design that reduces resonance or\"drone\" at low RPM.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMore Power: + 6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM\u003c\/li\u003e\n\u003cli\u003eHelmholtz chamber to reduce drone\u003c\/li\u003e\n\u003cli\u003eEnjoyably louder, sportier sound\u003c\/li\u003e\n\u003cli\u003eTwin 89mm (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 2\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 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLabor Time (Hours):\u003c\/strong\u003e 1.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 48\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 6 @ 6600 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Torque (lb-ft) Gain:\u003c\/strong\u003e 5 @ 6600 RPM\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\u003eTip Finish:\u003c\/strong\u003e Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":44849844486279,"sku":"DIND660-0077","price":2464.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/f70ce5d62905a2767aa870adb3cde9c5.jpg?v=1788268360","url":"https:\/\/checkout.northernperformance.ca\/products\/dinan-free-flow-axle-back-exhaust-2017-2020-bmw-440i","provider":"Northern Performance","version":"1.0","type":"link"}
