1-7/8 Stainless Steel LS Long-Tube Headers for Camaro/Firebird 1970-1981 and Nova/Ventura 1975-1979
When installing an LS motor into a 1970 to 1981 Camaro or a 1975 to 1979 Nova, routing exhaust tubes around the subframe and steering linkages can become a frustrating puzzle. The 1.875 inch stainless steel long tube headers tackle this with precision mandrel bends and thick 304 stainless flanges that weld directly into existing engine mounts for perfect LS engine compatibility. Each header also integrates O2 sensor bungs at factory port locations to simplify tuning and diagnostics from dyno to street use.
Precision Mandrel Bends for Consistent LS Exhaust Flow
Mandrel bending preserves the full 1-7/8 inch diameter through every curve, preventing internal deformation that occurs with crushed or kinked bends. This smooth routing around the subframe and steering linkages eliminates turbulence and reduces back pressure, promoting efficient cylinder scavenging. As exhaust pulses exit at evenly timed intervals, the engine breathes more freely, translating to stronger low-end torque and increased peak horsepower. Consistent pulse tuning also yields repeatable dyno results and reliable street performance.
304 Stainless Steel Construction Resists Heat and Corrosion
Fabricated from premium 304 stainless steel, these headers withstand oxidation and repeated thermal cycling far better than mild steel counterparts. The high chromium and nickel content maintains structural integrity under extreme temperatures, preventing warping or premature failure. This durability extends the service life of your headers, minimizing maintenance and replacement intervals. Owners benefit from sustained performance and a corrosion-free finish that complements vintage Camaro, Firebird, Nova, and Ventura styling.
Thick Flange Integration for Leak Free Sealing
With precision-machined 3/8 inch flanges, these headers provide a flat, stable mating surface that resists distortion under clamping loads and heat expansion. The extra thickness maintains consistent torque on the studs, working in concert with the included gaskets to eliminate common leak paths. Stable sealing ensures smoother idle quality and sharper throttle response by preventing pressure loss at the cylinder head interface. This robust design reduces the need for frequent retorquing or leak repairs.
Built-In O2 Sensor Ports for Simplified Tuning
Each primary tube features a welded O2 sensor bung positioned at the factory exhaust port location, enabling direct installation of your existing sensors without adapters. This precise placement delivers accurate air fuel ratio data straight from the header, critical for both dyno calibration and street tuning. By integrating the bungs into the 304 stainless tubes, the design avoids additional leak paths and preserves structural strength. Technicians save time on installation and achieve more accurate engine management mapping.
These headers deliver a precise fit and durable performance for your LS conversion.
