Dyno tuned for maximum exhaust flow with minimum backpressure, this system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle, thanks to computer-controlled valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow. The exhaust gasses exit through larger laser engraved polished, or ceramic black, quad tips.\u003c\/p\u003e\u003cp\u003eStainless Steel - Polished Tips - F80\/F82\/F83\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eComputer controlled valve limits noise during low speed driving; valve opens fully during high-load conditions to allow free flow\u003c\/li\u003e\n\u003cli\u003eTwin secondary exhaust valves with a whopping 76mm diameter, making them 45% less restrictive than the OE valves.\u003c\/li\u003e\n\u003cli\u003eOperation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-Drive settings.\u003c\/li\u003e\n\u003cli\u003eQuad 3.5\" black ceramic coated, or polished stainless, laser engraved exhaust tips\u003c\/li\u003e\n\u003cli\u003eUses the factory brackets and hangers for a factory-like fitment\u003c\/li\u003e\n\u003cli\u003eDrone abatement technologies used to reduce cabin resonance\u003c\/li\u003e\n\u003cli\u003eDinan exhaust is 3 lbs lighter than stock\u003c\/li\u003e\n\u003cli\u003eStock exhaust valve actuaters are reused\u003c\/li\u003e\n\u003cli\u003e100% 304 stainless steel construction\u003c\/li\u003e\n\u003cli\u003eEnjoyably louder, sporter sound\u003c\/li\u003e\n\u003cli\u003eMore Power: +5 HP\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":47948428411031,"sku":"dnnD660-0050","price":1228.18,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0497\/9697\/2695\/files\/21a594a488b137f632b2683caa8aefc0L.jpg?v=1782384768","url":"https:\/\/nlpperformance.com\/en-ca\/products\/dinan-15-18-bmw-m3-freeflow-axleback-exhaust-system-polished","provider":"Next Level Performance","version":"1.0","type":"link"}
