Our mirror polished SS304 valved catback is a street-track upgrade for G80 M3\/G82 M4\/G87 M2. Smooth mandrel bent piping removes factory flow bottlenecks, balancing backpressure to lift horsepower, torque and throttle response. OEM-synchronized electronic valves work with stock drive modes: closed valves deliver quiet drone-free daily cruising; open valves unleash crisp race roar with natural exhaust pops under acceleration. Full airtight TIG welding guarantees stable heat resistance, glossy black quad tips upgrade rear sport styling, and OEM matching brackets support bolt-on installation without cutting or modification.\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\u003eBMW M3 Sedan (G80)\u003c\/strong\u003e — All Years (3.0L S58 Twin-Turbo Inline Six Engine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW M4 Coupe (G82) \/ M4 Convertible (G83)\u003c\/strong\u003e — All Years (3.0L S58 Twin-Turbo Inline Six Engine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW M2 (G87)\u003c\/strong\u003e — All 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\u003eMirror Polished Premium SS304 Stainless Steel Tubing:\u003c\/strong\u003e Corrosion \u0026amp; heat resistant seamless mandrel bent pipes, eliminate OEM flow restrictions for better power output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Synchronized Intelligent Valvetronic System:\u003c\/strong\u003e Fully compatible with factory drive mode valve control, two sound modes for daily commute and track racing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo Tunable Acoustic Profiles:\u003c\/strong\u003e Valves closed delivers refined low-frequency quiet tone without cabin drone; valves open releases crisp exotic race roar with natural exhaust pops \u0026amp; crackles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGloss Black Quad Straight Exhaust Tips:\u003c\/strong\u003e Four glossy black tail tips create bold aggressive rear racing appearance for G8X chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfessional Full TIG Seamless Air-Tight Welding:\u003c\/strong\u003e Smooth internal welds reduce airflow turbulence, fully sealed joints prevent exhaust leakage 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 flanges, no cutting, welding or custom fabrication required.\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 Mirror Polished High Grade SS304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type:\u003c\/strong\u003e OEM Synchronized Electronic Valvetronic (Vehicle Stock Drive Mode Control)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Style:\u003c\/strong\u003e Quad Gloss Black Straight 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 Polished SS304 Valvetronic Catback Exhaust Assembly\u003c\/li\u003e\n\u003cli\u003e4x Gloss Black Straight Exhaust Tip Sleeves\u003c\/li\u003e\n\u003cli\u003eOEM Matching Valve Control Wiring Harness (Compatible with Factory ECU)\u003c\/li\u003e\n\u003cli\u003eFull Set Installation Clamps, Rubber Hangers \u0026amp; Mount Hardware Kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Wanmax Racing","offers":[{"title":"Default Title","offer_id":54919189889396,"sku":null,"price":925.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/7244\/2740\/files\/H7de3562a11d24874a94d2e50bf2042f4y.jpg?v=1783646632","url":"https:\/\/wanmaxracing.com\/products\/polished-ss304-valvetronic-catback-exhaust-system-for-bmw-g80-m3-g82-m4-g87-m2-s58-3-0l-with-gloss-black-tips","provider":"Wanmax Racing","version":"1.0","type":"link"}
