Due to the engine's long cylinder head profile, the OEM units undergo extreme thermal expansion and contraction cycles that the original cast iron or low-grade steel cannot accommodate, inevitably leading to structural cracking—most commonly near the collectors. These cracks cause significant exhaust leaks, which skew O2 sensor data, trigger CELs, and reduce fuel economy. Furthermore, the stock log-style design creates excessive backpressure by forcing exhaust pulses to collide, trapping heat in the cylinder head and limiting the low-end torque necessary for off-road performance.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis header system is engineered from mandrel-bent T-304 stainless steel, providing superior corrosion resistance and the structural integrity needed to withstand high EGTs (Exhaust Gas Temperatures). The 6-2 design features individual 1.50-inch manifold ports that transition into a 1.75-inch major piping diameter, significantly reducing turbulence and increasing air flow velocity. Every joint is TIG welded for maximum seam strength, while the CNC-machined flanges ensure a perfectly flat mating surface to prevent future leaks. By improving the scavenging effect, this system allows the engine to breathe more efficiently, resulting in an instant gain of 10-15 horsepower and torque while effectively pulling heat away from the engine block.\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;\"\u003e2000-2006 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 PowerTech) \/ 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;\"\u003eUT10563MA067TE\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eT-304 Full Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet\/Outlet\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.50\" Port \/ 1.75\" Piping\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 6-Cylinder\u003c\/li\u003e\n  \u003cli\u003e2001 Jeep Wrangler 4.0L 6-Cylinder\u003c\/li\u003e\n  \u003cli\u003e2002 Jeep Wrangler 4.0L 6-Cylinder\u003c\/li\u003e\n  \u003cli\u003e2003 Jeep Wrangler 4.0L 6-Cylinder\u003c\/li\u003e\n  \u003cli\u003e2004 Jeep Wrangler 4.0L 6-Cylinder\u003c\/li\u003e\n  \u003cli\u003e2005 Jeep Wrangler 4.0L 6-Cylinder\u003c\/li\u003e\n  \u003cli\u003e2006 Jeep Wrangler 4.0L 6-Cylinder\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for the rigors of both daily driving and rock crawling, these headers provide the mechanical reliability required for the 4.0L Inline-6.
