Full wrapped metal mesh heat shielding effectively locks high exhaust heat, protecting undercarriage wiring and rubber parts from thermal aging damage. Built-in flexible pipe section absorbs engine vibration to avoid weld fatigue. Produced with 1:1 chassis jig molding to match factory mounting positions completely, supporting direct OEM bolt-on installation without cutting or modification. Uniform fish-scale TIG airtight welding ensures stable long-term performance under extreme high temperature.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eVEHICLE FITMENT\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercedes-Benz CLS550 \u003c\/strong\u003e— 2012-2018 All Production Years (M278 4.7T Twin Turbo V8 Engine)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy Gauge Premium T304 Stainless Steel Construction:\u003c\/strong\u003e Thick mandrel bent pipe wall with excellent anti-rust and high-temperature resistance, long service life under continuous high heat conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Wrap Metal Mesh Thermal Insulation Layer:\u003c\/strong\u003e Effectively isolates radiant turbo exhaust heat, prevents surrounding plastic and wiring components from heat aging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Large Bore High Flow Internal Geometry:\u003c\/strong\u003e Minimizes internal gas flow resistance to speed up turbo spool and sharpen throttle sensitivity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-In Flexible Pipe Section:\u003c\/strong\u003e Buffers engine displacement vibration, avoids weld cracking during long-term intense driving.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1:1 Chassis Jig Precision Mold Design:\u003c\/strong\u003e Every pipe bend and sensor port matches OEM chassis data for seamless plug-and-play setup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Hand Fish-Scale TIG Air-Tight Welding:\u003c\/strong\u003e Smooth uniform welds maintain airtight seal under sustained extreme exhaust heat, no abnormal rattling or gas leakage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eTECH SPECIFICATIONS\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMain Pipe Material:\u003c\/strong\u003e Thick Mandrel Bent T304 Stainless Steel with Mirror Polished Surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Treatment:\u003c\/strong\u003e Full Wrap Metal Mesh Heat Shield Insulation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Set:\u003c\/strong\u003e Left \u0026amp; Right Front Downpipe Pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlex Section:\u003c\/strong\u003e Integrated Braided Flexible Pipe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWelding Process:\u003c\/strong\u003e Handcrafted Full Fish-Scale TIG Seamless Air-Tight Welding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine:\u003c\/strong\u003e M278 4.7T Twin Turbo V8 (2012-2018 CLS550)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eWHAT'S IN THE BOX\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e1 Pair Complete Heat Shielded SS304 High Flow Front Downpipe Assembly\u003c\/li\u003e\n\u003cli\u003eFull Set OEM Matching Installation Clamps \u0026amp; Hardware Kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Wanmax Racing","offers":[{"title":"Default Title","offer_id":54968210588020,"sku":null,"price":490.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/7244\/2740\/files\/H9e36977973cb4618a19dbe67e5c1cd3az_1_ab07a570-9bba-46ec-b3f7-8094838f2a64.jpg?v=1784181419","url":"https:\/\/wanmaxracing.com\/products\/heat-shielded-ss304-high-flow-front-downpipe-for-mercedes-benz-cls550-m278-4-7t-v8-2012-2018","provider":"Wanmax Racing","version":"1.0","type":"link"}
