Coupled with a Dinan exhaust however they become a symphony of aural delight that even the most discerning ear will find pleasing. \nDinan's Free Flow axle-back exhaust system features 100% stainless steel construction measured to exact specifications to ensure proper fit via factory hangers and mounting points. 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.\nEvery Dinan product comes with our industry-exclusive factory matching new car bumper to bumper warranty and is designed and tested in Morgan Hill, California and can be purchased and installed at any Dinan Approved BMW dealership nationwide.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMore Power: +5 HP\u003c\/li\u003e\n\u003cli\u003eDrone abatement technologies used to reduce cabin resonance\u003c\/li\u003e\n\u003cli\u003eEnjoyably louder, sporter sound\u003c\/li\u003e\n\u003cli\u003eQuad 3.5\" black ceramic coated, or polished stainless, laser engraved exhaust tips\u003c\/li\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\u003eStock exhaust valve actuaters are reused\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\u003eDinan exhaust is 3 lbs lighter than stock\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\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\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eApplication:\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eYear\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eMake\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSubmodel\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eEngine Size\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2015\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2015\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eSpecs:\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eDinan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDinan Point Value\u003c\/th\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEmission Code\u003c\/th\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeight\u003c\/th\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLabor Time (Hours)\u003c\/th\u003e\n\u003ctd\u003e1.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003e304 Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax HP Gain\u003c\/th\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eAxle-Back Exhaust\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSound Level\u003c\/th\u003e\n\u003ctd\u003eAggressive \/ Moderate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSystem Type\u003c\/th\u003e\n\u003ctd\u003eAxle-back\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarning\u003c\/th\u003e\n\u003ctd\u003eCalifornia Proposition 65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e56\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWidth\u003c\/th\u003e\n\u003ctd\u003e34\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":39324909043761,"sku":"D660-0050-BLK","price":2254.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2493\/0960\/files\/dinan-free-flow-ss-exhaust-for-15-19-bmw-f80-m3-f82-f83-m4-d660-0050-blk-modern-day-muffler-1.jpg?v=1738841618","url":"https:\/\/moderndaymuffler.com\/products\/dinan-free-flow-ss-exhaust-for-15-19-bmw-f80-m3-f82-f83-m4-d660-0050-blk","provider":"Modern Day Muffler","version":"1.0","type":"link"}
