On the G20\/G22 platform, a full catback exhaust is not required because the factory midpipe is single-piece, non-restrictive, and free of cats and resonators. Replacing it offers no real performance or sound gain, making the axleback the smart focus for upgrade.\u003c\/p\u003e\n\u003cp data-start=\"1126\" data-end=\"1342\"\u003eThis system enhances your vehicle’s sound character while retaining the factory midpipe. You’ll enjoy a deeper, more aggressive tone when accelerating, yet it remains refined and comfortable during regular driving.\u003c\/p\u003e\n\u003cp data-start=\"1344\" data-end=\"1474\"\u003eThe exhaust comes with three tip options: brushed stainless, black, or carbon, allowing you to customize the look to your build.\u003c\/p\u003e\n\u003cp data-start=\"1476\" data-end=\"1637\"\u003eInstallation is simple and quick. Cutting the factory pipe is required, but the process is straightforward, and the included clamps ensure a clean, secure fit.\u003c\/p\u003e\n\u003cp data-start=\"1639\" data-end=\"1788\"\u003eConstructed from high-quality 304L stainless steel, this axleback provides excellent durability and corrosion resistance for long-term performance.\u003c\/p\u003e\n\u003cp data-start=\"1790\" data-end=\"2129\"\u003eThe system includes an upgraded dual valve setup that converts the factory single valve into a true M-style dual valve configuration. The factory valve actuator is reused, and an additional valve is added on the opposite side. This allows your exhaust to function seamlessly with OEM drive modes—quiet in Comfort and fully open in Sport.\u003c\/p\u003e\n\u003ch3 data-start=\"2131\" data-end=\"2146\"\u003eFeatures:\u003c\/h3\u003e\n\u003cul data-start=\"2147\" data-end=\"2661\"\u003e\n\u003cli data-start=\"2147\" data-end=\"2199\"\u003e\n\u003cp data-start=\"2149\" data-end=\"2199\"\u003eSlip-on axleback design for BMW M340i and M440i.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2200\" data-end=\"2267\"\u003e\n\u003cp data-start=\"2202\" data-end=\"2267\"\u003eDramatic sound improvement while retaining the factory midpipe.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2268\" data-end=\"2326\"\u003e\n\u003cp data-start=\"2270\" data-end=\"2326\"\u003eDual valve upgrade for true M-style exhaust operation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2327\" data-end=\"2395\"\u003e\n\u003cp data-start=\"2329\" data-end=\"2395\"\u003eOEM drive modes retained: quiet in Comfort, fully open in Sport.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2396\" data-end=\"2456\"\u003e\n\u003cp data-start=\"2398\" data-end=\"2456\"\u003eThree tip finishes: brushed stainless, black, or carbon.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2457\" data-end=\"2539\"\u003e\n\u003cp data-start=\"2459\" data-end=\"2539\"\u003eMade from premium 304L stainless steel for corrosion resistance and longevity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2540\" data-end=\"2604\"\u003e\n\u003cp data-start=\"2542\" data-end=\"2604\"\u003eQuick and straightforward installation with included clamps.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2605\" data-end=\"2661\"\u003e\n\u003cp data-start=\"2607\" data-end=\"2661\"\u003eValue-focused design with no unnecessary components.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"2663\" data-end=\"2677\"\u003eFitment:\u003c\/h3\u003e\n\u003cul data-start=\"2678\" data-end=\"2764\"\u003e\n\u003cli data-start=\"2678\" data-end=\"2701\"\u003e\n\u003cp data-start=\"2680\" data-end=\"2701\"\u003e2019-2024 BMW M340i\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2702\" data-end=\"2725\"\u003e\n\u003cp data-start=\"2704\" data-end=\"2725\"\u003e2019-2024 BMW M440i\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2726\" data-end=\"2764\"\u003e\n\u003cp data-start=\"2728\" data-end=\"2764\"\u003eAll models include xDrive variants\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe MAD BMW M340i M440i Axleback Exhaust delivers maximum sound impact, M-style performance, and clean, hassle-free installation, making it the ultimate upgrade for discerning BMW enthusiasts\u003c\/p\u003e","brand":"Mastery of Art and Design","offers":[{"title":"Brushed","offer_id":42177228636245,"sku":"MAD-147 + MAD-147-BR","price":1229.0,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":42177228669013,"sku":"MAD-147 + MAD-147-BLK","price":1379.0,"currency_code":"USD","in_stock":true},{"title":"Carbon Fiber","offer_id":42177228701781,"sku":"MAD-147 + MAD-147-CA","price":1379.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0074\/3702\/5395\/files\/kies-motorsports-mastery-of-art-and-design-mad-bmw-m340-m440-axleback-exhaust-g20-g22-1237083899.jpg?v=1778181209","url":"https:\/\/www.kiesmotorsports.com\/products\/mad-bmw-m340-m440-axleback-exhaust-g20-g22","provider":"Kies Motorsports","version":"1.0","type":"link"}
