Progressive carbon contamination from normal engine blow-by masks the OEM ceramic core, leading to elevated exhaust backpressure, choked high-RPM flow, increased cylinder head temperatures, and catalyst efficiency check-engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement assembly utilizes a high-grade stainless steel outer casing encasing a uniform ceramic honeycomb substrate engineered for rapid thermal light-off and stable hydrocarbon conversion. Heavy-gauge, laser-aligned connection flanges match factory drop points without requiring custom pipe bending or welding, while integrated oxygen sensor ports and included hardware restore an airtight, leak-free exhaust seal.\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;\"\u003e2009-2013 Hyundai Sonata\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;\"\u003eTheta II (G4KC \/ G4KE \/ G4KJ) \/ NF \u0026amp; YF\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;\"\u003e175-198 hp \/ 168-184 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;\"\u003eBER388725 (Interchange: 10H40963)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHyundai Sonata (2009-2013):\u003c\/strong\u003e 2.4L L4 Engine Configuration, Front Placement, Direct Replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Hyundai Commuter Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for dependable urban driving and strict emissions readiness, this manifold-downpipe converter assembly maintains correct backpressure dynamics for smooth engine response and clean, no-CEL operation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50488063820024,"sku":"DS-EEGHV6Z2C","price":114.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-hyundai-sonata-2009-2013-2-4l-1.jpg?v=1789148448","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-hyundai-sonata-2009-2013-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
