1-7/8 Ceramic Coated LS Mid-Length Headers for A-Body
For LS conversions in 1968 to 1972 A Body projects, these ceramic coated mid length headers navigate chassis tight spots by routing 1.875 inch exhaust primaries around steering linkages and suspension components without trimming or special adapters. Their full three eighth inch steel flanges align with factory engine mounts and standard LS mount kits for dependable sealing and even clamping pressure across the head surface. A silver ceramic barrier finish reflects radiant heat back into the exhaust path while guarding the tubes from moisture and road salts, keeping bay temperatures down and corrosion at bay. Technicians will appreciate the precise fit that simplifies installation, reduces installation time, and delivers consistent performance in street or track use.
Precision Mandrel Bent Tubing for Uninterrupted Exhaust Gas Flow
The mandrel bending process used on each 1.875 inch primary tube creates a seamless curve that preserves the full interior diameter through every turn. By eliminating constrictions and sharp transitions, these headers promote efficient scavenging of exhaust gases, helping to draw fresh air and fuel into the combustion chamber more effectively. The result is a smoother torque curve at low engine speeds and a crisper throttle response when accelerating. Tight fabrication tolerances ensure the tubes match in length and shape on both banks, providing consistent pulse timing and balanced flow. Enthusiasts will notice more linear power delivery on the street and stable performance under hard acceleration on the track. This design not only boosts output but also enhances engine breathing efficiency without compromising compatibility with LS mount kits.
Three Eighth Inch Steel Flanges Deliver Reliable Seal Integrity
Each flange is formed from three eighth inch thick steel, offering the rigidity required to resist warping under repeated heat cycles. The substantial mass of the flange holds its flatness against the cylinder head, enabling even clamp force across the full gasket surface. When torqued to specifications, this produces a leak proof joint that maintains stable back pressure and suppresses noise and emissions escaping at the header-to-head interface. Installers benefit from the precise alignment with factory mounting points and standard LS mount kit hardware, which reduces adjustment time and eliminates the need for shims or custom modifications. Over months of use, the robust flange construction stands up to thermal expansion and contraction, ensuring the seal remains tight and dependable. This engineered approach safeguards both performance and longevity in daily driving or spirited track sessions.
Ceramic Barrier Coating for Thermal Control and Corrosion Resistance
The silver ceramic barrier finish applied to each tube reflects radiant heat back into the exhaust stream, lowering temperatures in the engine bay and protecting nearby components. Cooler underhood conditions extend the life of intake plenums, electrical wiring, and ignition parts while supporting a denser air charge for improved combustion efficiency. At the same time, the ceramic layer seals the underlying steel against moisture, road salt, and other corrosive elements to prevent rust formation. This dual advantage promotes consistent performance over many seasons and preserves the appearance of the headers even under harsh environmental exposure. Technicians appreciate that the coating adheres evenly to complex bends and welds, maintaining its protective properties without flaking or degradation. The result is a set of headers that combines thermal management with durable corrosion defense, ideal for both daily drivers and high stress applications.
