LS 1-7/8 Long-Tube Headers for Camaro/Firebird 1970-1981 and Nova/Ventura 1975-1979
When fitting an LS into a vintage Camaro or Firebird the exhaust path can make or break the installation. The 1-7/8 Stainless Steel Long-Tube Headers streamline flow with precision bent 304 stainless tubing and robust flanges that resist warping under heat. Each unit comes with O2 sensor bungs positioned for factory exhaust ports to simplify tuning. Installation uses original engine mounts and custom fit dimensions for 1970 to 1981 Camaro and Firebird or 1975 to 1979 Nova and Ventura ensuring reliable performance for your swap.
Precision Mandrel Bent Tubing Maximizes Exhaust Velocity
The continuous curvature of the mandrel bent 1-7/8 inch tubes preserves internal diameter through each bend, eliminating flow restrictions that occur with crushed or kinked bends. This smooth path allows exhaust gases to exit the cylinder head more efficiently, reducing back pressure and improving scavenging effect. As a result, drivers experience measurable gains in both horsepower and torque across the rpm range. By maintaining consistent tube geometry, these headers deliver a consistent pulse wave that enhances overall engine breathing.
Robust 304 Stainless Steel Resists Corrosion And Heat
Manufactured from premium 304 stainless steel, these headers offer superior resistance to rust and oxidation compared to mild steel or budget alloys. The high chromium and nickel content in 304 grade ensures the metal maintains structural integrity and resists warping when exposed to repeated heat cycles. This durability translates into a longer service life even under demanding driving conditions. Vehicle owners benefit from lower maintenance requirements and sustained performance without the need for frequent replacement.
Thick 3/8 Inch Flanges Deliver Reliable Sealing
The precision cut 3/8 inch flanges provide a flat, stable mating surface against the cylinder head, minimizing the risk of exhaust leaks under extreme temperatures. Thicker flanges resist distortion and maintain clamping force when torqued to specification, eliminating common leak points found in thinner designs. Combined with the included custom-fitted gaskets, this flange construction ensures consistent sealing and prevents pressure loss. The result is smoother idle quality and improved throttle response.
Integrated O2 Sensor Bungs Streamline Engine Calibration
Each header features strategically positioned O2 sensor bungs that align with factory exhaust port locations, allowing direct installation of sensors without adapters or relocation kits. This positioning ensures accurate air fuel ratio readings and simplifies the tuning process for custom engine management systems. By welding these bungs into the primary tubes, the design maintains structural strength and avoids potential leak paths. Technicians save time during dyno tuning and street calibration, resulting in a more precise setup.
Engineered for a precise fit and lasting performance in your Camaro or Firebird LS swap.
