Over high mileage cycles, the OEM ceramic washcoat suffers attrition, and rich exhaust transients trigger core thermal meltdown or substrate fracturing. This deterioration produces internal exhaust flow restriction, elevated backpressure that throttles scavenging efficiency, and downstream catalytic efficiency trouble codes (P0420\/P0430).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM manifold and downpipe dimensions, this complete converter assembly utilizes high-grade stainless steel tubing for maximum oxidation and corrosion resistance against road brine and off-road moisture. Internally, a high-porosity ceramic honeycomb substrate coated with precious catalytic metals ensures uniform exhaust gas distribution, rapid light-off temperatures, and clean stoichiometric conversion without choking high-RPM gas velocity. Precision-welded flanges guarantee a leak-free seal to factory mounting points.\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;\"\u003e2000-2003 Jeep Wrangler\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;\"\u003ePowerTech 4.0L I6 (AMC 242) \/ TJ\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;\"\u003e190 hp \/ 235 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000 Jeep Wrangler 4.0L Inline-6 (TJ)\u003c\/li\u003e\n  \u003cli\u003e2001 Jeep Wrangler 4.0L Inline-6 (TJ)\u003c\/li\u003e\n  \u003cli\u003e2002 Jeep Wrangler 4.0L Inline-6 (TJ)\u003c\/li\u003e\n  \u003cli\u003e2003 Jeep Wrangler 4.0L Inline-6 (TJ)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Off-Road Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand continuous low-range rock crawling and heavy towing demands, this exhaust assembly resists mechanical shock, prevents floorboard heat transfer, and maintains critical backpressure balance for consistent low-end crawl torque.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50489476907256,"sku":"DS-ESR0074CC","price":257.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-jeep-wrangler-2000-2003-4-0l-1.jpg?v=1789163088","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-jeep-wrangler-2000-2003-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
