This design forces exhaust pulses from opposing cylinders into violent collision, causing backpressure reversion, localized heat soak, and restricted exhaust gas velocity above 4,500 RPM. The uneven primary runners leave residual combusted gases inside the chambers, hindering volumetric efficiency and raising combustion temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis header assembly addresses factory flow restrictions by incorporating mandrel-bent stainless steel primary tubes engineered for uniform runner length and smooth interior flow paths. Finished in a resilient black thermal coating, the assembly isolates heat to lower engine bay temperatures while preserving exhaust pulse velocity. Thick, laser-cut mounting flanges resist thermal warpage and maintain flat mating surfaces against the cylinder heads under high thermal expansion cycles. Precision-engineered merge collectors equalize scavenging pressures across all cylinders, reducing pumping losses and maximizing engine breathing efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2010-2016 Hyundai Genesis\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eLambda II 3.8L V6\u003c\/strong\u003e \/ \u003cstrong\u003eBK\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e306-348 hp \/ 266-295 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010-2016 Hyundai Genesis Coupe 3.8L V6 (Base, Track, R-Spec, Grand Touring, Ultimate)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the BK Genesis?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2010-2016 Hyundai Genesis Coupe equipped with the \u003cstrong\u003eLambda II 3.8L V6\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs an ECU tune required after installing this header assembly?\u003c\/strong\u003e\u003cbr\u003e While the vehicle will operate on factory fuel trims, a custom ECU calibration is recommended to correct air-fuel ratios and extract maximum performance from the increased scavenging efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hyundai Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-revving naturally aspirated applications, this header kit delivers the aggressive acoustic profile, structural durability, and sustained flow capacity required for demanding track and spirited rear-wheel-drive street driving.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50512354246904,"sku":"DS-EML3U6I02","price":446.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-header-for-hyundai-genesis-2010-2016-3-8l-1.jpg?v=1789426085","url":"https:\/\/performancechiptuning.com\/products\/exhaust-header-for-hyundai-genesis-2010-2016-3-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
