The Dinan exhausts feature rigid and durable muffler cases manufactured from 20 gauge 304 stainless steel for optimum corrosion resistance. Internally, the systems feature Dinan's Tuned Resonance Chamber Technology providing the optimum balance between maximum power gains and a civilized, yet sporty exhaust note. The Dinan exhausts also provide substantial weight reduction compared to the stock mufflers. The mufflers weigh in at 18.5 lbs. compared to the stock systems at 34 lbs. Dual 3-inch diameter polished stainless steel exhaust tips give the cars a tasteful performance look as well.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMore Power: + 7 HP @ 6500 RPM + 6 LB-FT @ 6500 RPM (w\/ 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\u003eDual 3\" polished and laser engraved exhaust tips\u003c\/li\u003e\n\u003cli\u003eOver 15 lbs. lighter than stock (18.5 lbs. vs. 34 lbs.)\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 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLabor Time (Hours):\u003c\/strong\u003e 1.5\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 7 @ 6500 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Torque (lb-ft) Gain:\u003c\/strong\u003e 6 @ 6500 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 37.5\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":44849874239623,"sku":"DIND660-3940","price":1446.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/51f51e20217703330c37866b0b8d5f3a.jpg?v=1788268375","url":"https:\/\/checkout.northernperformance.ca\/products\/dinan-free-flow-axle-back-exhaust-1997-2003-bmw-540i","provider":"Northern Performance","version":"1.0","type":"link"}
