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. This is accomplished thanks to a computer-controlled valve that limits noise during low-speed driving and opens fully during high-load conditions to allow free flow. For maximum enjoyment and sound when the valve is opened on the M2 exhaust the system becomes a straight pipe to achieve peak power, flow and tone. No matter if the valve is open or closed the exhaust gasses make their exit via Dinan's signature enlarged, laser engraved, black ceramic quad tips. Not only will your M2 sound breathtaking, but it will also look the part as well.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eStainless Steel - F87\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eMaximum gain of +6 HP and +5 LB-FT of torque\u003c\/li\u003e\n\u003cli\u003eSportier sound\u003c\/li\u003e\n\u003cli\u003eQuad 3.5\" laser engraved black ceramic tips with Dinan logo\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 actuators are reused\u003c\/li\u003e\n\u003cli\u003eWhen valve is open, exhaust flows straight through 3.25\" tubing\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","brand":"Dinan","offers":[{"title":"Default Title","offer_id":53417270346027,"sku":"D660-0056-BLK","price":2193.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/3645\/4465\/files\/1_47019acd-e768-4a5c-8848-27664f3d223c.png?v=1779966663"},{"product_id":"freeflow-exhaust-f33-f36-435-b","title":"Dinan BMW 435i 14-16 Free Flow Axle-Back Exhaust - Polished Tips","description":"\u003cp\u003eDinan engineers designed the F30 340i and F32 440i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration.

To date, Dinan has been synonymous with welded on, thin-walled tips and a philosophy of exuding a civilized note when you want it to be, and a pleasantly aggressive one under hard acceleration. While the mantra is maintained, albeit tweaked with the emergence of mid-pipes and resonator deletes to those who want an even more aggressive sound, the styling of the tips is being drastically transformed. The new massive 4\" diameter tips on the M550i exhaust are the biggest we have done thus far in addition to being double-walled the polar opposite of our normal thin-walled style. Perhaps most importantly however is the new tips are clamp-on. Not welded as in the past, so they can be easily swapped to new styles or replaced as the need arises.\u003c\/p\u003e\n\u003cp\u003eInternally, the exhaust is typical of other Dinan exhausts and is designed to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow. Like all Dinan exhausts, our M550i Free Flow Axle-Back Exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. In fact, on the G30 M550i equipped with a Dinan exhaust, you will be astounded at how eerily quiet it is in the cabin. That is quickly changed however when exiting the vehicle and being witness to the sporty luxury sedan revving its stout V8 engine with the exhaust valves wide open. Blissfully bellowing a sweet deep tone that begs for more is the reward.

To date, Dinan has been synonymous with welded on, thin-walled tips and a philosophy of exuding a civilized note when you want it to be, and a pleasantly aggressive one under hard acceleration. While the mantra is maintained, albeit tweaked with the emergence of mid-pipes and resonator deletes to those who want an even more aggressive sound, the styling of the tips is being drastically transformed. The new massive 4\" diameter tips on the M550i exhaust are the biggest we have done thus far in addition to being double-walled the polar opposite of our normal thin-walled style.

The combination results in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow and greater sound as the bulk of the gases are bypassing the muffler. Like all Dinan exhausts, our X5M\/X6M free flow exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. With the Dinan exhaust equipped on the X5M\/X6M you get the best of both worlds; aggressive tone\/sound and civility. A combination that is quintessential of the luxury SUV with a penchant for aggressive behavior.\u003c\/p\u003e\n\u003cp\u003eSound isn't the only aspect of the exhaust that has been modified. The Dinan F9x X5M\/X6M exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color. The entire system is then brush finished to further guarantee an immaculate looking system out of the box. The attention to detail is not limited to parts of the system you can't see once the exhaust is installed but is also extended to the exhaust tips themselves. The Dinan exhaust sports massive, quad 4.5\" (114mm) clamp-on, double-walled, polished stainless steel and laser engraved exhaust tips that are befitting of the big Bavarian beast. The tips masterfully fill up and accentuate upon the factory cut-outs showcasing an extremely aggressive, yet refined, styling that will force people to take notice even before it is heard.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eStainless Steel - F95\/F96\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eMaximum gains of +6 HP and +5 ft-lb of torque\u003c\/li\u003e\n\u003cli\u003eEnjoyably louder, sportier sound\u003c\/li\u003e\n\u003cli\u003eDrone abatement technologies used to reduce cabin resonance\u003c\/li\u003e\n\u003cli\u003eFour, diffuser filling, 4.5\" (114mm) double-walled, polished stainless steel clamp-on tips with laser engraved Dinan logo\u003c\/li\u003e\n\u003cli\u003eLarger diameter piping for increased flow (83mm vs. 80mm)\u003c\/li\u003e\n\u003cli\u003eStock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings\u003c\/li\u003e\n\u003cli\u003eComputer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions\u003c\/li\u003e\n\u003cli\u003eTwin secondary exhaust valves are a whopping 76mm diameter, making them 30% less restrictive than the OE valves\u003c\/li\u003e\n\u003cli\u003e100% 304 Stainless Steel construction\u003c\/li\u003e\n\u003cli\u003eFactory-like fitment with included mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":53417273164075,"sku":"D660-0090-BLK","price":2882.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/3645\/4465\/files\/3_f27bf52f-9c5b-43fc-ada8-9fcbe07b7f8d.png?v=1779960603"}],"url":"https:\/\/www.burton-racing.com\/collections\/exhaust-system-kit\/g87.oembed","provider":"Burton-Racing","version":"1.0","type":"link"}
