Cast iron manifolds are engineered for low manufacturing costs rather than optimal flow dynamics. Their rough internal casting flash and sharp internal transitions create severe exhaust turbulence, significantly reducing the naturally aspirated engine's scavenging efficiency. Over decades of thermal cycling, these heavy cast components become highly susceptible to heat soak and stress fractures, often cracking at the webbing between the exhaust ports. Furthermore, the dense cast iron retains excessive engine bay heat, exacerbating the thermal degradation of surrounding engine components.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eUpgrading to a tubular 4-1 header design resolves these fundamental airflow limitations. Constructed from corrosion-resistant stainless steel, this header features precision-mandrel bent 1.375-inch primary tubes that optimize exhaust gas velocity, merging smoothly into a 2.00-inch outlet. This targeted primary sizing promotes superior exhaust scavenging, actively pulling spent gases from the combustion chamber to yield verified gains of 5-10 horsepower and proportionate torque increases. To eliminate the risk of flange warping—a common issue with aftermarket headers—this unit utilizes robust CNC-machined flanges, measuring a massive 7\/16-inch thick at the cylinder head and 3\/8-inch at the outlet. The assembly is meticulously TIG and MIG welded for maximum structural integrity and includes the necessary O2 sensor bung, gaskets, bolts, and clamps for a complete mechanical upgrade.\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;\"\u003e1986-1988 Ford Ranger\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;\"\u003eFord 2.0L OHC Pinto I4 \/ 1st Gen\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;\"\u003e73 hp \/ 107 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\u003eFord Ranger Pickup Truck (1986) - 2.0L Engine\u003c\/li\u003e\n    \u003cli\u003eFord Ranger Pickup Truck (1987) - 2.0L Engine\u003c\/li\u003e\n    \u003cli\u003eFord Ranger Pickup Truck (1988) - 2.0L Engine\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFitment Note:\u003c\/strong\u003e Driver Side Exhaust Models ONLY\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Ford Ranger Utility Standard\u003c\/h3\u003e\n  \u003cp\u003eFor a reliable workhorse like the first-generation Ranger, optimizing low-end torque and long-term durability is essential.
