Continuous thermal expansion cycles cause washcoat sintering, micro-fracturing of the ceramic core, and reduction of noble metal surface contact. Over time, restricted exhaust pathways increase backpressure against the cylinder heads, driving up exhaust gas temperatures (EGTs), diminishing low-end torque output, and triggering check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-on assembly, this unit features a heavy-gauge 409 stainless steel housing designed to withstand extreme thermal stress, road debris impact, and structural corrosion. Inside, an emissions-grade ceramic honeycomb substrate delivers high-efficiency catalytic reduction with minimal exhaust restriction. Precision-formed flanges and integrated factory-profile mounting brackets ensure an accurate seal to stock exhaust manifolds, retaining factory oxygen sensor bung locations without requiring cutting or custom welding.\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;\"\u003e2013-2019 Jeep Grand Cherokee\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;\"\u003e3.6L Pentastar V6 \/ WK2\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;\"\u003e295 hp \/ 260 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;\"\u003eBER514290 (OE: 68036556AG, 68110124AE, 68303469AB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013-2019 Jeep Grand Cherokee 3.6L V6 (All Trims)\u003c\/li\u003e\n  \u003cli\u003ePlacement: Left and Right side assembly\u003c\/li\u003e\n  \u003cli\u003eDirect Interchange OE Numbers: 679-549, 54926, 679-548, 68036556AG, 68110124AE, 68303469AB, 68037894AE, 68037894AF, 68110125AE, 68036556AE\u003c\/li\u003e\n  \u003cli\u003eIncludes direct-fit mounting hardware, clamps, and installation gaskets\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the vibration and heavy load demands of trail use and towing, this assembly maintains structural integrity and leak-free emissions sealing under severe operating conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50489053937912,"sku":"DS-EU80KF9VE","price":236.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-jeep-grand-cherokee-2013-2019-3-6l-1.jpg?v=1789156673","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-jeep-grand-cherokee-2013-2019-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
