All while remaining emissions-compliant. Presenting the second generation of SwitchPath™ Exhaust for the BMW F8X M3 and M4.\u003c\/p\u003e\n\u003cp\u003eMinimal bends, maximum flow, and push-button attitude. The SwitchPath™ Exhaust is a true catback configuration comprised of 3-inch and 2.5-inch U.S.-sourced T304L stainless steel, a precision x-pipe, and a valved SwitchPath™ muffler tuned specifically for the S55.\u003c\/p\u003e\n\u003cp\u003eBeginning after the secondary catalysts, the precision X-pipe immediately helps smooth the S55 of its infamous rasp, allowing the tone to be further refined by the bespoke muffler in the rear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe closed valve experience:\u003c\/strong\u003e\u003cbr\u003eWhen the valves are closed, the SwitchPath™ Exhaust produces a refined, aggressive howl while remaining full-bodied and powerful – no congested, metallic sounds here when on the throttle. At cruising speeds, interior acoustics are close to stock. AWE SwitchPath™ tech also responds perfectly to the many transmission settings and shift points in DCT 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe opened valve experience:\u003c\/strong\u003e\u003cbr\u003eOpen the valves and the S55’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…a lot of 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.\u003c\/p\u003e\n\u003cp\u003eIf you’re looking for the best of both worlds and want to retain your factory valve behavior all while gaining peace of mind (i.e. emissions compliance), look no further than SwitchPath™.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUnified design for OPF euro and non-euro spec cars (2015 - 2020 fitments confirmed)\u003c\/li\u003e\n\u003cli\u003e50-state legal catback design: sick sound with all catalysts intact\u003c\/li\u003e\n\u003cli\u003ePrecision-engineered X-pipe to unlock a clean S55 tone\u003c\/li\u003e\n\u003cli\u003eSwitchPath™ utilizes factory valving and retains M-Sport button functionality\u003c\/li\u003e\n\u003cli\u003e3” CNC mandrel-bent catback configuration\u003c\/li\u003e\n\u003cli\u003eMax gains of 12 hp and 16 ft-lbs of torque at the wheels\u003c\/li\u003e\n\u003cli\u003eTip options include 102mm double-walled, slash-cut tips in chrome silver\u003c\/li\u003e\n\u003cli\u003eHandcrafted from U.S.-sourced .065\"\" wall T304L stainless steel\u003c\/li\u003e\n\u003cli\u003eProudly engineered, designed, and manufactured in-house at AWE\u003c\/li\u003e\n\u003cli\u003eNo Check Engine Light Guarantee\u003c\/li\u003e\n\u003cli\u003ePerfect Fitment Guarantee\u003c\/li\u003e\n\u003cli\u003eFeaturing the AWE Lifetime Exhaust Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConfiguration: SwitchPath Catback Exhaust\u003c\/li\u003e\n\u003cli\u003eMaterial: T304L Stainless Steel\u003c\/li\u003e\n\u003cli\u003eTubing Diameter: 3”\u003c\/li\u003e\n\u003cli\u003eExhaust Tip Diameter: 4\" \u003c\/li\u003e\n\u003cli\u003eExhaust Tip Finish: Chrome Silver Tips\u003c\/li\u003e\n\u003cli\u003eConstruction: CNC Mandrel-Bent, .065” wall thickness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e(1) AWE Tuning SwitchPath Cat-Back Exhaust w\/ 4\" Chrome Tips\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2015-2018 BMW M3 Base 3.0L\u003c\/li\u003e\n\u003cli\u003e2015-2020 BMW M4 Base 3.0L\u003c\/li\u003e\n\u003cli\u003e2019-2020 BMW M4 CS 3.0L\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AWE Tuning","offers":[{"title":"Default Title","offer_id":46779053834397,"sku":"3025-42070","price":2775.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/3025-42070.png?v=1747164192","url":"https:\/\/rudysdiesel.com\/products\/awe-switchpath-cat-back-exhaust-w-4-chrome-tips-for-15-20-bmw-m3-m4-3-0l","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
