1-7/8 Stainless Steel Long-Tube LS Headers for Camaro/Firebird 1970-1981 and Nova/Ventura 1975-1979
If you are converting a 1970s Camaro or Firebird or an X body Nova or Ventura with a modern LS power plant, routing the 1-7/8 Stainless Steel Long Tube Headers past subframe rails and steering linkages can stall projects for days. These headers wrap around the F body and X body chassis with exact tucks and consistent tube diameter throughout. Each mandrel bent tube keeps the 1 7/8 inch diameter intact and bolts to the head with thick 304 stainless flanges for a precise fit. O2 sensor bungs installed at factory locations cut installation time and ensure accurate tuning on dyno or road tests.
Mandrel Bent Tube Geometry Ensuring Uniform LS Exhaust Flow
The 1-7/8 inch tubes are mandrel bent to maintain a constant diameter through each curve, eliminating any internal crimping or kink that can impede gas flow. By preserving smooth contours around the subframe rails and steering linkages, these headers reduce turbulence and back pressure, which helps exhaust pulses exit in a consistent sequence. That consistency enhances cylinder scavenging, delivering stronger low-rpm torque and a more linear powerband. As a result, drivers notice improved throttle response and repeatable dyno numbers every run. This precision bending also simplifies alignment during installation, allowing the tubes to follow the chassis contours without excess trimming.
304 Stainless Steel Construction for Durable Heat and Corrosion Resistance
These headers are crafted from premium 304 stainless steel, selected for its high chromium and nickel content that withstands repeated thermal cycles without distortion. Unlike mild steel, this alloy resists oxidation and maintains tensile strength at elevated exhaust temperatures, preventing warping under heavy load. The material's inherent corrosion resistance also means these headers retain their fit and finish over years of road salt, humidity and track abuse. Vehicle owners benefit from minimal maintenance and a consistently clean appearance under the hood. In combination with factory-grade welds, the stainless steel structure delivers lasting reliability for any LS swap application.
Precision Thick Flanges Deliver Leak Free Cylinder Head Sealing
Featuring 3/8 inch precision-machined flanges, these headers create a flat, stable mating surface that resists deformation under exhaust heat and vibration. Thicker flanges maintain clamp load on the studs, ensuring the included gaskets compress evenly to prevent exhaust leaks at the head interface. Stable sealing avoids pressure loss that can dull throttle feel and reduce efficiency, especially during engine warm-up. Technicians report fewer retorquing cycles and a noticeable improvement in idle smoothness thanks to the consistent seal. By eliminating common leak paths, this flange design contributes to both quiet operation and maximum power transfer.
Factory Positioned O2 Sensor Bungs Simplify Tuning and Diagnostics
Each primary tube comes with an integrated sensor bung located at the original factory port, enabling direct installation of existing O2 sensors without adapters or extensions. This exact placement delivers accurate air-fuel ratio readings right at the header exit, which is critical for both dyno calibration and precise engine management adjustments on the street. Welding the bung into the 304 stainless tubing eliminates potential leak sites and preserves structural integrity. Tuners save hours of alignment and bracket fabrication by plugging straight into the vehicle's factory harness. The result is faster, more accurate mapping and reliable performance monitoring under all driving conditions.
These headers deliver a precise fit and reliable performance for your LS swap project.
