Not only is the tone improved but the additional burbles and pops that also accompany it are simply intoxicating. While on the exterior the sound may be viewed as aggressive the inside of the cabin is still civil courtesy of an incorporated 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\u003e2 massive quadrilateral black ceramic coated tips with laser engraved Dinan logo\u003c\/li\u003e\n\u003cli\u003e100% 304 stainless steel construction\u003c\/li\u003e\n\u003cli\u003eFactory computer controlled valve is eliminated for maximum flow and sound at all times\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 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLabor Time (Hours):\u003c\/strong\u003e 1.3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 55\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\u003eSub Category:\u003c\/strong\u003e Exhaust and Tail Pipes\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":44849846190215,"sku":"DIND660-0078-BLK","price":2869.93,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/a29dd65fb7bb2efa43bef8799725633c.jpg?v=1788268360","url":"https:\/\/checkout.northernperformance.ca\/products\/dinan-free-flow-axle-back-exhaust-2017-2023-bmw-540i","provider":"Northern Performance","version":"1.0","type":"link"}
