Our WANMAX Racing fully heat-wrapped SS304 catless downpipe solves both issues at once. The one-piece seamless mandrel bent tubing with 89mm to 76mm tapered diameter optimizes exhaust flow to speed up turbo spool, unlock extra power and unleash a raw, aggressive S55 turbo tone. Full integrated heat shield wrapping traps high exhaust heat inside the pipe, lowering under-hood temperatures to protect wiring, plastics and intake parts. Precision CNC flanges deliver a leak-free bolt-on fit with zero cutting or fabrication required.\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 (F80)\u003c\/strong\u003e — 2014–2018 (3.0L S55 Twin-Turbo I6)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW M4 Coupe (F82) \u003c\/strong\u003e— 2014–2020 (3.0L S55 Twin-Turbo I6)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW M4 Convertible (F83)\u003c\/strong\u003e — 2014–2020 (3.0L S55 Twin-Turbo I6)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW M2 Competition (F87) \u003c\/strong\u003e— 2018–2021 (3.0L S55 Twin-Turbo I6)\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\u003eFull Heat Shield Wrapped Exterior: \u003c\/strong\u003ePremium multi-layer heat insulation wrap contains exhaust heat, reduces engine bay temperature and protects nearby sensitive components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatless High Flow Layout:\u003c\/strong\u003e Eliminates OEM restrictive catalytic converters to slash exhaust backpressure, boost turbo response and amplify sporty exhaust sound.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e89mm to 76mm Tapered Reducer Pipe: \u003c\/strong\u003eSmooth gradual diameter transition optimizes exhaust gas velocity for consistent power delivery and faster turbo spool.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-Piece Integrated Mandrel Bend:\u003c\/strong\u003e Seamless single bend construction removes internal flow barriers for smoother airflow and stronger structural integrity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium SS304 Stainless Steel Material:\u003c\/strong\u003e Corrosion and heat resistant 304 stainless steel, long service life under harsh high-temperature conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Full TIG Welding:\u003c\/strong\u003e Air-tight seamless weld joints to prevent exhaust leaks even under extreme track heat.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100% Direct Bolt-On Installation: \u003c\/strong\u003eFactory matched flange mounting points, pre-installed O2 sensor bungs, no modification, cutting or welding needed.\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 Grade SS304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size: \u003c\/strong\u003eTapered 89mm Inlet to 76mm Outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction: \u003c\/strong\u003eOne-Piece Mandrel Integrated Bend\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Treatment:\u003c\/strong\u003e Full Multi-Layer Heat Shield Wrap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration: \u003c\/strong\u003eCatless High Flow Turbo Downpipe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWelding: \u003c\/strong\u003eProfessional Full TIG Seamless Weld\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 S55 3.0L Twin Turbo Straight 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\u003e2x Heat Shield Wrapped SS304 Turbo Downpipes (Left \u0026amp; Right Pair)\u003c\/li\u003e\n\u003cli\u003ePre-Welded OEM Standard O2 Sensor Bungs\u003c\/li\u003e\n\u003cli\u003eComplete Set of Installation Mounting Bolts \u0026amp; Hardware\u003c\/li\u003e\n\u003cli\u003eOEM Matching Precision CNC Flanges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Wanmax Racing","offers":[{"title":"Default Title","offer_id":54913226506612,"sku":"WMR-M3F80-DP-HS-001","price":329.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/7244\/2740\/files\/Hfa28a63134f041b792575a145d7c38adm.jpg?v=1783577221","url":"https:\/\/wanmaxracing.com\/products\/heat-shield-wrapped-catless-ss304-turbo-downpipe-for-bmw-f80-m3-f82-f83-m4-f87-m2-competition-s55-3-0t-2014-2020","provider":"Wanmax Racing","version":"1.0","type":"link"}
