Headers for LT In 70-81 F-Body 1.875in Uncoated

Hedman Headers for LT In 70-81 F-Body with 1.875-inch uncoated long-tube design delivers serious exhaust scavenging for classic Camaro and Firebird platforms. These headers are engineered to maximize exhaust gas velocity from second-generation F-Body engines, offering measurable gains in peak horsepower and mid-range torque. The uncoated stainless steel construction provides durability without thermal coating, making these headers a cost-effective choice for street and strip applications where raw performance matters.

The 1.875-inch primary tubes are sized to match the scavenging characteristics of small-block and big-block engines common to 1970–1981 F-Body vehicles, flowing exhaust at optimal velocities across the RPM range. The collector step to 3 inches provides smooth transition and minimizes backpressure. Stainless steel resists corrosion better than mild steel alternatives, particularly important for vehicles stored seasonally or driven in humid climates. At 37.1 pounds total weight, this pair requires proper clearance planning during installation—exhaust routing, transmission cooler lines, and suspension components demand careful fitment on original and modified engine bays.

These headers suit enthusiasts restoring or modifying 1970–1981 Chevrolet Camaro and Pontiac Firebird models seeking bolt-on performance gains without welding or fabrication. Long-tube headers for F-Body applications require exhaust system planning downstream of the collector—whether feeding into a traditional two-piece exhaust system, modern cat-back components, or full custom exhaust. Fitment varies with engine displacement, transmission type, and frame-mounted accessories, so pre-purchase verification against your specific vehicle configuration is essential.

Hedman is established in the long-tube header market for classic American muscle cars, with products engineered for both stock and modified powerplants. The uncoated finish eliminates cost and weight of thermal coating while accepting that stainless steel naturally oxidizes—regular maintenance preserves appearance. This header set represents a proven platform for second-gen F-Body enthusiasts balancing performance, budget, and installation complexity.
