Over time, internal matrix clogging elevates exhaust backpressure, choking cylinder scavenging, reducing fuel efficiency, and triggering persistent P0420 catalytic efficiency diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement converter features a high-grade ceramic honeycomb substrate washcoated with precious metal loadings designed to meet OBD-II\/OBD-3 emissions thresholds. Encased in a heavy-gauge, corrosion-resistant stainless steel body, the direct-fit assembly utilizes laser-cut OE-style flanges, factory-location oxygen sensor bungs, and pre-aligned hanger points. Included hardware and sealing gaskets ensure leak-free exhaust gas velocity and reliable emissions performance.\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;\"\u003e2010-2014 GMC Terrain\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;\"\u003e2.4L Ecotec (LAF \/ LEA) \/ GM Theta Platform\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;\"\u003e182 hp \/ 172 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;\"\u003eBER454020 (Interchange: 12609823, 1804, 19463, 54850)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010 GMC Terrain 2.4L L4 (SLE, SLT)\u003c\/li\u003e\n  \u003cli\u003e2011 GMC Terrain 2.4L L4 (SLE, SLT)\u003c\/li\u003e\n  \u003cli\u003e2012 GMC Terrain 2.4L L4 (SLE, SLT)\u003c\/li\u003e\n  \u003cli\u003e2013 GMC Terrain 2.4L L4 (Denali, SLE, SLT)\u003c\/li\u003e\n  \u003cli\u003e2014 GMC Terrain 2.4L L4 (Denali, SLE, SLT)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Professional-Grade Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained daily commuting and heavy utility loads, this catalytic converter delivers robust thermal endurance to eliminate CEL triggers and protect engine efficiency across high mileage.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50484787249400,"sku":"DS-EEWMBFR2Q","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-gmc-terrain-2010-2014-2-4l-1.jpg?v=1789105887","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-gmc-terrain-2010-2014-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
