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 we all knew there is world class sound lying under all the rasp. Our mission has been to find this hidden sound and allow all F8x owners to enjoy it. This full catback is comprised of an 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 our 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\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eSound Devlopments. \u003c\/strong\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eAt Valvetronic Designs, we are chasing perfection and we believe this our equal-length exhaust setup is the sound solution for F8x owners. Traditionally equal length exhaust configuartion lowers the aggressive nature of the S55 engine. With this new design we have spent countless hours testing to ensure the raw aggressive sound is present through all rev ranges to give that emotion, but with 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 setups volume.  \u003c\/p\u003e\n\u003ch3\u003eFeatures of this Valved Exhaust \u003c\/h3\u003e\n\u003cdiv class=\"included-list\"\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\u003c\/div\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eVehicle Fitment: \u003c\/h3\u003e\n\u003ctable data-mce-fragment=\"1\" style=\"border-collapse: collapse;
