Over time, the stock ceramic substrates degrade, suffering from thermal shock, matrix core fracturing, or poisoned washcoats that inevitably trigger recurring P0420 and P0430 diagnostic trouble codes. Furthermore, factory mild-steel welds fatigue near the collector junction, producing exhaust leaks that distort upstream oxygen sensor readings and choke low-end torque.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete direct-fit Y-pipe converter assembly is constructed from high-grade stainless steel with an integrated high-flow ceramic honeycomb substrate. Precision-loaded catalyst formulations ensure optimal hydrocarbon and NOx conversion while maintaining unrestricted exhaust flow. Engineered with heavy-gauge OE-style flanges, precision-welded O2 sensor bungs, and pre-aligned hanger brackets, it bolts straight to existing manifold outlets without custom fabrication or cutting.\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;\"\u003e2004-2006 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;\"\u003eAMC 242 (4.0L I6) \/ 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\u003e2004-2006 Jeep Wrangler (TJ \/ LJ Unlimited) 4.0L Inline-6 (Sport, Sahara, Rubicon, SE, X)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Trail-Ready Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand rock crawling, washboard trails, and severe off-road flex, this replacement assembly delivers the structural rigidity and thermal resistance required to keep your 4.0L powertrain running clean and efficient under heavy load.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50489473466616,"sku":"DS-EY830ERGH","price":245.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-jeep-wrangler-2004-2006-4-0l-1.jpg?v=1789163060","url":"https:\/\/performancechiptuning.com\/products\/catalytic-converter-for-jeep-wrangler-2004-2006-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
