1-7/8 Stainless Steel Mid-Length Headers for LS Engine Swaps
When space is tight in an LS swap the 1-7/8 Stainless Steel Mid-Length Headers deliver precise exhaust routing that clears common interference points. Crafted from 304 stainless steel tubing the smooth runners resist corrosion and retain shape under repeated heat cycles for dependable exhaust flow. Installation becomes straightforward thanks to precision machined three eighths inch flanges and built-in O2 sensor bungs that align with factory mount points on LS blocks.
Precision Runner Lengths for Improved Exhaust Scavenging
The 1-7/8-inch primary tubes are cut to exact lengths that align with the pulse pattern of an LS V8, enhancing scavenging across the rpm range. By matching each runner to the engine's firing order, back pressure is reduced and throttle response becomes sharper under load. This balanced flow allows spent gases to evacuate more efficiently, which in turn smooths out the powerband for both street cruising and spirited driving. The result is a noticeable gain in low-end torque without sacrificing top-end performance and everyday drivability.
304 Stainless Steel Construction for Corrosion Resistance
Crafted from premium 304 stainless steel, these headers resist oxidation and corrosion even after repeated heat cycles and exposure to road elements. The alloy's natural resistance to rust keeps the tubes looking and performing like new, while its strength under thermal stress prevents warping or cracking. A polished interior surface promotes consistent exhaust flow and makes removal of debris or road salt a simple task. This material choice ensures the headers maintain shape and integrity for years of reliable service.
Integrated O2 Sensor Bungs for Streamlined Tuning
Welded directly into the collector, the built in O2 sensor bungs eliminate the need for adapters or aftermarket fittings. This precise placement guarantees accurate readings for both factory and wideband sensors, allowing tuners to refine air-fuel ratios with confidence. Eliminating extra components also reduces potential leak points, preserving exhaust integrity. Technicians will appreciate the faster setup and the ability to dial in optimal power and efficiency without guesswork.
Thick Machined Flanges for Leak Free Sealing
Each flange is machined to a robust three eighths inch thickness, creating a rigid mating surface that resists distortion under heat and torque. The added mass ensures even gasket crush and minimizes the need for retorquing after initial installation. By maintaining a consistent seal at the cylinder head, these headers prevent exhaust leaks that can degrade performance and increase cabin noise. The precise flange finish simplifies alignment during installation, delivering a dependable connection that stands up to demanding LS swap applications.
These headers offer reliable sealing and consistent exhaust flow for your LS engine swap.
