As the factory washcoat degrades, precious metal loading depletes, preventing the secondary catalyst from neutralizing unburned hydrocarbons and carbon monoxide downstream of the manifold converter. This progressive degradation causes internal substrate crumbling, exhaust backpressure spikes, and recurring P0420 fault codes that trigger check engine warnings and fail state emissions inspections.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement unit features a heavy-gauge 409 stainless steel housing designed to withstand extreme thermal expansion cycles and exterior road-salt corrosion without seam failure. Internally, a dense, high-flow ceramic honeycomb substrate coated with an optimized washcoat facilitates rapid catalytic light-off and maximizes exhaust scrubbing efficiency while minimizing exhaust backpressure. Precision-cut, thick OE-style flanges match the factory downpipe and mid-pipe connections perfectly, while the included hardware and replacement seals ensure a leak-free, bolt-on installation without cutting or custom fabrication, directly restoring stock \u003cstrong\u003eBeta II (G4GC)\u003c\/strong\u003e exhaust flow dynamics.\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;\"\u003e2007-2012 Hyundai Elantra 2.0L (Rear Position)\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;\"\u003eBeta II (G4GC) \/ HD\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;\"\u003e138 hp \/ 136 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;\"\u003e16533\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007 Hyundai Elantra 2.0L Rear (Sedan)\u003c\/li\u003e\n  \u003cli\u003e2008 Hyundai Elantra 2.0L Rear (Sedan)\u003c\/li\u003e\n  \u003cli\u003e2009 Hyundai Elantra 2.0L Rear (Sedan, Touring)\u003c\/li\u003e\n  \u003cli\u003e2010 Hyundai Elantra 2.0L Rear (Sedan, Touring)\u003c\/li\u003e\n  \u003cli\u003e2011 Hyundai Elantra Touring 2.0L Rear (Wagon)\u003c\/li\u003e\n  \u003cli\u003e2012 Hyundai Elantra Touring 2.0L Rear (Wagon)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the HD Elantra?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2007-2012 Hyundai Elantra equipped with the 2.0L \u003cstrong\u003eBeta II (G4GC)\u003c\/strong\u003e engine in the rear downstream exhaust location.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this resolve downstream P0420 catalytic efficiency codes?\u003c\/strong\u003e\u003cbr\u003e Provided upstream oxygen sensors and air-fuel mixtures are within spec, this fresh high-efficiency ceramic substrate clears emissions-related catalyst failure codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hyundai Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver long-term service life and quiet factory tone, this emissions assembly restores fuel efficiency, clean combustion compliance, and reliable daily operation for commuter-driven Hyundai platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50501087854840,"sku":"DS-EU59471RM","price":135.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-hyundai-elantra-2007-2012-2-0l-rear-1.jpg?v=1789325968","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-hyundai-elantra-2007-2012-2-0l-rear","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
