{"product_id":"exhaust-valve-controller","title":"Exhaust Valve Controller","description":"The MAD Exhaust Valve Controller Essential provides manual override capability for factory electronic exhaust valves, enabling drivers to bypass the automated factory system. By allowing users to lock valves at 100% open, 50% open, or fully closed, this controller offers consistent sound management and minimizes unwanted rasp or drone regardless of drive mode or throttle input.\n\nConstructed for long-term durability, the module features an IP68 waterproof rating for safe mounting inside the trunk or under the vehicle. It utilizes a military-spec wiring harness with a heat-resistant sheath and includes a plug-and-play connection that requires no cutting, tapping, or permanent vehicle modifications. A memory function ensures your last valve setting is retained upon vehicle restart.\n\nThe kit includes two premium remotes and supports seamless integration with factory HomeLink buttons. A dummy plug is provided for vehicles with single-valve exhaust systems to ensure universal compatibility with various BMW F and G chassis models. Important fitment note: this controller is exclusively compatible with F-chassis models equipped with electronic valves.","brand":"MAD","offers":[{"title":"Default Title","offer_id":52662866805048,"sku":"MAD-144","price":159.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687071271.webp?v=1784321631","url":"https:\/\/store.motormia.co\/products\/exhaust-valve-controller","provider":"MOTORMIA","version":"1.0","type":"link"}
