For years enthusiasts have wanted to find a solution to the buzzy and raspy sound these cars produce from the factory. Since these cars were released back in the late portions of 2014, enthusiasts knew there was world class sound lying under all the rasp. Valvetronic's mission has been to find this hidden sound and allow all F8x owners to enjoy it. This full catback is comprised of a 2.75\" equal length mid section with an H pipe configuration. After traveling through the H pipe the exhaust is combined into a 3.5-inch axle back. This combination helps smooth the exhaust tones to provide a very enjoyable sound through the entire rev range. When operating with the valves open, the exhaust gases exit unrestricted out of the passenger side exhaust tips. With the valves closed the exhaust passes through the quad chambered muffler and out of the drivers side exhaust tips for a lower volume experience, very well suited to daily driving and not alerting the Karens. This system mounts up to factory mounting points and is a direct bolt-on. No cutting or welding necessary. It's time to make the F8x sound like it always should have.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eSound Developments. \u003c\/strong\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eAt Valvetronic Designs, the engineers are chasing perfection, and this equal-length exhaust setup is the sound solution for F8x owners. Traditionally equal length exhaust configuration lowers the aggressive nature of the S55 engine. With this new design Valvetronic spent countless hours testing to ensure the raw aggressive sound is present through all rev ranges to give that emotion, but the equal length configuration allows for the sound to be very pleasurable rather than just loud. Owners coming from other non-equal length setups will not feel short-changed in regards to this setup's volume. \u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"text-align: left;\"\u003ePRODUCT SPECIFICATION\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eConstructed from T304 Stainless Steel or titanium\u003c\/li\u003e\n\u003cli\u003eElectronic exhaust valves for factory-like operation \u003c\/li\u003e\n\u003cli\u003e21.7 lbs Lighter than the factory exhaust \u003c\/li\u003e\n\u003cli\u003eFully Mandrel bend for maximum flow\u003c\/li\u003e\n\u003cli\u003ePrecision tig welds for high strength\u003c\/li\u003e\n\u003cli\u003e100% REVERSABLE, always able to go back to stock at any time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 style=\"text-align: left;\"\u003eCOMPATIBILITY\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e2015 - 2018 BMW M3 F80\u003c\/li\u003e\n\u003cli\u003e20\u003cspan data-mce-fragment=\"1\"\u003e15 - 2020 BMW M4 F82\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e2015 - 2020 BMW M4 F83\u003c\/li\u003e\n\u003c\/ul\u003e \u003cem\u003e\u003cstrong\u003eDISLAIMER: Valvetronic Designs is an aftermarket exhaust manufacturer based in the USA.
