In place of the factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes which are commonplace in the market. This sophisticated 'X' is not only the focal point of the system in terms of aesthetics but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is found in stock systems. Along with the inherent benefit of increased volume by removal of the resonator, the Dinan Middle Exhaust for the G30 M550i produces a louder, smoother and fuller exhaust note.\nStainless Steel - 3\" - G30\nOnly confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems.

Crafted from durable 304 stainless steel, this 3-inch (76mm) exhaust system replaces the factory mid-section, including the resonator, with mandrel-bent T304 stainless steel tubing designed for maximum flow and minimal restriction. The larger diameter tubing ensures improved exhaust flow, which can contribute to increased horsepower and torque, delivering a more responsive driving experience. The centerpiece of this system is the meticulously designed X-pipe crossover, made from mandrel-bent tubing, which balances exhaust flow between both banks of the engine, eliminating uneven sound nuances common in stock systems. This not only results in a more even and aggressive exhaust note but also reduces turbulence for smoother operation. The modifications promote a louder, fuller, and sportier sound profile, perfect for enthusiasts seeking a more engaging driving experience. This bolt-on installation integrates seamlessly with the factory system when paired with the Dinan Free Flow Axle Back, offering a straightforward upgrade without extensive modifications. Hardware for mounting is included, making the process straightforward for both professional and DIY installers. Please note that this system is not CARB approved and is intended for off-road or track use only. Designed exclusively for the specified model years, this exhaust system is a significant upgrade for drivers looking to improve both the sound and flow characteristics of their BMW M550i xDrive.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eIncludes X-pipe crossover made from mandrel bent tubing for minimum restriction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDeletes resonator between catalyst and rear muffler for increased volume\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e3 inch (76mm) tubing replaces stock 70mm tubing for enhanced free flow\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed from 100% 304 stainless steel for durability and corrosion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMounting hardware included for easy bolt-on installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProduces a smoother, sportier, and louder exhaust note\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned to fit 2018-2023 BMW M550i xDrive (G30 models) when paired with Dinan Free Flow Axle Back\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFitments:\u003cbr\u003e\n2018 BMW M550i xDrive Base\u003cbr\u003e\n2019 BMW M550i xDrive Base\u003cbr\u003e\n2020 BMW M550i xDrive Base\u003cbr\u003e\n2021 BMW M550i xDrive Base\u003cbr\u003e\n2022 BMW M550i xDrive Base\u003cbr\u003e\n2023 BMW M550i xDrive Base\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: true\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: true\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: t\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":50978716156156,"sku":"D660-0080","price":1599.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/4cb151775e60e7cd3e479014fa96a6acL.jpg?v=1786675694","url":"https:\/\/diycustoms.store\/products\/dinan-18-23-bmw-m550i-xdrive-g30-high-flow-middle-exhaust-kit-3-inch-stainless-steel","provider":"diycustoms.store","version":"1.0","type":"link"}
