No drone, minimal bends, maximum flow, and push-button attitude. The SwitchPath™ Exhaust is comprised of 3-inch U.S.-sourced T304L stainless steel, a precision x-pipe, and a valved SwitchPath™ muffler tuned specifically for the S58. Beginning after factory mid pipe, the precision X-pipe immediately helps smooth the S58 of its rasp, deepening the tone before its refined further by the bespoke SwitchPath™ muffler in the rear. When the valves are closed, the SwitchPath™ Exhaust produces a refined, aggressive howl while remaining full-bodied and powerful – no congested, metallic sounds when on the throttle. At cruising speeds, interior acoustics are close to stock with no drone at cruising speeds. AWE SwitchPath™ tech also responds perfectly to the many transmission settings and shift points in automatic vehicles. Drop the hammer with the valves closed and SwitchPath™ sings a proper M anthem. If you were to leave the valves closed at all times after equipping SwitchPath™, we wouldn’t blame you, it’s that good… all of the time. Open the valves and the S58’s roar is uncorked. Sport and Sport+ modes achieve the ultimate contrast in behavior when compared to comfort driving modes (valves closed). In Sport mode, the exhaust note is powerful, clean, and aggressive. In Sport+ mode, the same aggression applies… but with grin-provoking burbles. Thanks to the precision X-pipe, the rasp is still kept in check while allowing the exhaust note to reach full aggression.If you’re looking for the best of both worlds (i.e. drone-free, clean aggression), and want to retain your factory valve behavior all while gaining peace of mind (i.e. emissions compliance), look no further than SwitchPath™. And when it comes to showing off the party out back, the system comes with quad 4.5” double-walled, slash-cut tips available in chrome silver or diamond black.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSystem Type: Cat-Back Exhaust\u003c\/li\u003e\n\u003cli\u003eEdition: SwitchPath\u003c\/li\u003e\n\u003cli\u003eConfiguration: Dual 3 in with precision X-pipe and valved SwitchPath muffler, starts after the factory mid pipe\u003c\/li\u003e\n\u003cli\u003eTechnology: AWE 180 Technology drone cancellation\u003c\/li\u003e\n\u003cli\u003eValves: Retains factory valve controls, no remote needed\u003c\/li\u003e\n\u003cli\u003eTips: Quad 4.5 in double-walled slash-cut, Diamond Black\u003c\/li\u003e\n\u003cli\u003eValance: Fits stock and M-Performance valances\u003c\/li\u003e\n\u003cli\u003eEmissions: 50-state emissions compliant (per AWE)\u003c\/li\u003e\n\u003cli\u003eGains: Up to 3 hp and 5 lb-ft at the wheels\u003c\/li\u003e\n\u003cli\u003eMaterial: T304L stainless steel\u003c\/li\u003e\n\u003cli\u003eManufactured: In-house by AWE, USA\u003c\/li\u003e\n\u003cli\u003ePart Number: 3025-42480\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAWE's first SwitchPath™ Exhaust for BMW to incorporate drone-canceling 180 Technology®\u003c\/li\u003e\n\u003cli\u003eSwitchPath™ retains factory valve controls, no additional remote needed\u003c\/li\u003e\n\u003cli\u003eQuad 4.5” double-walled, slash-cut tips available in chrome silver\u003c\/li\u003e\n\u003cli\u003eLess is more: clean, straight-through design maximizes performance\u003c\/li\u003e\n\u003cli\u003eOptional non-resonated performance mid-pipes available separately\u003c\/li\u003e\n\u003cli\u003e50-state emissions-compliant dual 3” exhaust configuration\u003c\/li\u003e\n\u003cli\u003eMax gains of 3 hp and 5 lb-ft of torque at the wheels\u003c\/li\u003e\n\u003cli\u003eBespoke X-pipe unlocks a smooth tone out of the S58\u003c\/li\u003e\n\u003cli\u003eBall socket mounting points for easy installation\u003c\/li\u003e\n\u003cli\u003eFits stock and M-Performance valances\u003c\/li\u003e\n\u003cli\u003eAWE Perfect Fitment Guarantee\u003c\/li\u003e\n\u003cli\u003eManufactured in-house at AWE\u003c\/li\u003e\n\u003cli\u003eAWE Lifetime Warranty\u003c\/li\u003e\n\u003cli\u003eAWE No CEL Guarantee\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis Part Fits:\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2021-2026\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2021-2026\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3\u003c\/td\u003e\n\u003ctd\u003eCompetition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2022-2026\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3\u003c\/td\u003e\n\u003ctd\u003eCompetition xDrive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2024\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3\u003c\/td\u003e\n\u003ctd\u003eCS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2021-2026\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2021-2026\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003eCompetition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2022-2026\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003eCompetition xDrive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2025\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003eCS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2023\u003c\/td\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4\u003c\/td\u003e\n\u003ctd\u003eCSL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eDoes it keep the factory exhaust valves?\u003c\/h5\u003e\u003cp\u003eYes.
