Our mirror polished SS304 electronic valve catback exhaust is a reliable street and track performance upgrade for S58 SUV models. Built with CNC smooth mandrel bent stainless steel tubing, this system minimizes airflow turbulence to cut backpressure and unlock extra horsepower gains. Dual synchronized valve structure supports two sound control modes: wireless remote control or vehicle factory drive modes, allowing you to switch between quiet drone-free daily cruising tone and loud aggressive racing exhaust roar at will. Full airtight professional TIG welding guarantees long-term leak-proof performance under continuous high-temperature driving. Matched quad carbon fiber tail tips upgrade the rear sport appearance, and OEM matching mounting brackets enable straightforward bolt-on installation without cutting or modification. Bulk order custom laser logo engraving service is available on mufflers and carbon tips for tuning shop distributors.\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\u003eBMW X3M (F97)\u003c\/strong\u003e — All Production Years (3.0L S58 Twin-Turbo Inline Six Engine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW X4M (F98)\u003c\/strong\u003e — All Production Years (3.0L S58 Twin-Turbo Inline Six Engine)\u003cbr\u003e\n\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\u003ePremium Mirror Polished SS304 Stainless Steel Tubing:\u003c\/strong\u003e High corrosion \u0026amp; heat resistant polished steel with seamless mandrel bends, durable for long-term high-temperature driving conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Synchronized Intelligent Valvetronic Control System:\u003c\/strong\u003e Compatible with wireless remote \u0026amp; OEM drive modes dual control, freely switch quiet daily sound and loud track racing tone.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuad Matte Carbon Fiber Exhaust Tips:\u003c\/strong\u003e Four carbon fiber tail tips upgrade rear aggressive sport styling, deliver a customized high-performance visual effect.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Professional TIG Seamless Air-Tight Welding:\u003c\/strong\u003e Smooth internal welds eliminate airflow turbulence, all joints fully sealed to prevent exhaust leaks under sustained heat.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100% Direct OEM Bolt-On Fitment:\u003c\/strong\u003e Precision CNC bent pipes match factory hangers and flange positions, no cutting, welding or custom fabrication required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom Laser Logo Engraving Support:\u003c\/strong\u003e Accept custom laser logo marking on mufflers and carbon tips for bulk wholesale orders, flexible MOQ \u0026amp; fast global shipping.\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\u003eMaterial:\u003c\/strong\u003e High Mirror Polished SS304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type:\u003c\/strong\u003e Synchronized Dual Electronic Valvetronic (Remote \u0026amp; OEM Drive Mode Dual Control)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Style:\u003c\/strong\u003e Quad Matte Carbon Fiber Tail Tips\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Type:\u003c\/strong\u003e High Flow Valved Catback Exhaust System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWelding Process:\u003c\/strong\u003e Full Handcrafted TIG Seamless Air-Tight Welding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment Type:\u003c\/strong\u003e OEM Direct Bolt-On Replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine:\u003c\/strong\u003e S58 3.0L Twin-Turbo Inline Six\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\u003e1x Complete SS304 Valvetronic Catback Exhaust Assembly\u003c\/li\u003e\n\u003cli\u003e4x Carbon Fiber Exhaust Tip Sleeves\u003c\/li\u003e\n\u003cli\u003eElectronic Valve Control Module \u0026amp; Dual Wireless Remote Fobs\u003c\/li\u003e\n\u003cli\u003eFull Set OEM Matching Installation Clamps, Rubber Hangers \u0026amp; Hardware Kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Wanmax Racing","offers":[{"title":"Default Title","offer_id":54914161443188,"sku":null,"price":819.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/7244\/2740\/files\/H5f8db01bc2374dd28f1db01458c3a4ffn.jpg?v=1783647964","url":"https:\/\/wanmaxracing.com\/products\/polished-ss304-valvetronic-catback-exhaust-for-bmw-f97-x3m-f98-x4m-s58-3-0l-with-quad-carbon-tips","provider":"Wanmax Racing","version":"1.0","type":"link"}
