This degradation restricts downstream exhaust gas evacuation, inducing excessive backpressure that saps fuel economy and engine efficiency while illuminating diagnostic trouble codes. Additionally, road-salt exposure severely corrodes the OEM steel flanges, creating audible exhaust leaks and skewed oxygen sensor feedback.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed with a durable 409 stainless steel outer casing and a high-efficiency ceramic substrate, this direct-fit rear converter optimizes surface-area contact for reliable hydrocarbon and NOx reduction. Precision mandrel-bent tubing and CNC-machined bolt-on flanges ensure exact alignment with the OEM exhaust routing, eliminating the need for cutting or custom fabrication. Supplied hardware and replacement gaskets guarantee a sealed, leak-free exhaust connection with stock downstream backpressure profiles.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2011-2016 Hyundai Elantra 1.8L\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eNu 1.8L (G4NB) \/ MD, UD\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e148 hp \/ 131 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eBER638190 \/ 16646\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011 Hyundai Elantra (1.8L L4 - Sedan)\u003c\/li\u003e\n  \u003cli\u003e2012 Hyundai Elantra (1.8L L4 - Sedan)\u003c\/li\u003e\n  \u003cli\u003e2013 Hyundai Elantra (1.8L L4 - Sedan, Coupe)\u003c\/li\u003e\n  \u003cli\u003e2014 Hyundai Elantra (1.8L L4 - Sedan)\u003c\/li\u003e\n  \u003cli\u003e2015 Hyundai Elantra (1.8L L4 - Sedan)\u003c\/li\u003e\n  \u003cli\u003e2016 Hyundai Elantra (1.8L L4 - Sedan)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Hyundai Commuter Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to endure daily commuter thermal cycling, this bolt-on catalytic converter eliminates flow restrictions, restores factory tailpipe emissions integrity, and maintains clear, CEL-free operation under all driving conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50484872872184,"sku":"DS-EXZ7UOMSL","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-hyundai-elantra-2011-2016-1-8l-1.jpg?v=1789107618","url":"https:\/\/performancechiptuning.com\/es\/products\/catalytic-converter-for-hyundai-elantra-2011-2016-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
