These heavy 'log' style manifolds feature rough internal surfaces and sharp 90-degree transitions that create significant exhaust backpressure. Over thousands of heat cycles, the brittle cast iron is prone to stress cracking and flange warping, leading to persistent exhaust leaks. Mechanically, the stock design fails to utilize exhaust pulse tuning, meaning the engine must work harder to push spent gases out of the cylinders, which directly stifles low-end torque and overall thermal efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThese Phab headers are engineered from high-grade SUS-T304 stainless steel, featuring 1.5-inch primary tubes that provide a dedicated path for each cylinder's exhaust pulse. The 16-gauge (1.5mm) wall thickness ensures long-term durability against heat soak while maintaining the structural integrity required for heavy-duty truck applications. By utilizing mandrel-bent tubing, this system maintains a constant diameter through every curve, eliminating the flow restrictions found in the OEM parts. The 3\/8-inch thick CNC-machined flanges ensure a true, flat mating surface to the cylinder head, effectively preventing the leaks common with thinner, stamped-steel alternatives. The included stainless steel Y-pipe further streamlines the transition into the rest of the exhaust tract, facilitating faster gas velocity and improved throttle response.\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;\"\u003e1996-2003 Dodge Dakota, Ram, Durango\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;\"\u003e3.9L Magnum V6 \/ AN, BR, DN\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;\"\u003e175 hp \/ 225 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\u003e1996-2001 Dodge Ram 1500 3.9L V6 2WD\/4WD\u003c\/li\u003e\n  \u003cli\u003e1997-2003 Dodge Durango 3.9L V6 2WD\/4WD\u003c\/li\u003e\n  \u003cli\u003e1996-2003 Dodge Dakota 3.9L V6 2WD\/4WD\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Dodge Truck Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for the rigors of American truck ownership, these stainless headers provide the thermal stability needed for towing and off-road use.
