1-7/8-Inch Ceramic Coated LS Mid-Length Headers
For anyone retrofitting an LS engine into a 1968 to 1972 A Body sedan or coupe, these one and seven eighths inch ceramic coated mid length headers address tight frame rail clearance and exhaust routing conflicts. Formed from three eighths inch thick steel, each primary tube matches LS cylinder head ports and guides gases through a protective ceramic finish that reflects heat inward, lowering underhood temperature and resisting corrosion. Factory style flanges and supplied gaskets ensure a leak free seal without any modification or additional parts. The outcome is steady throttle response and consistent torque delivery across the entire rev range.
Robust Steel Flange for Reliable Exhaust Sealing
The three eighth inch thick steel flange matches LS cylinder head ports with precision, forming an uninterrupted seal that resists leakage even under intense heat cycles. Its mass and rigidity prevent warping as temperatures rise and fall, so gaskets remain compressed at an optimal level without constant adjustment. This stability ensures consistent torque delivery by keeping exhaust gases contained and directed through the system rather than escaping at the flange. Vibration from the classic A Body frame is absorbed without compromising the seal, delivering reliable operation mile after mile.
Ceramic Coating for Underhood Heat Management and Corrosion Resistance
A silver ceramic layer covers each primary tube and flange, reflecting radiant heat back into the exhaust stream to accelerate gas flow. By reducing underhood temperatures, the coating protects wiring, hoses and nearby components from heat soak and premature aging. It also creates a barrier that repels moisture and road debris, cutting down on oxidation and pitting over time. The finish preserves both the headers' appearance and structural integrity, so performance remains consistent season after season.
Optimized 1 7/8 Inch Primary Tube Sizing for Exhaust Flow Dynamics
The chosen tube diameter balances exhaust velocity and volume to support a broad torque curve. At low engine speeds, the sizing enhances scavenging in each cylinder, producing sharper throttle response around town or during gentle acceleration. As rpm climbs, backpressure remains low, enabling the LS engine to breathe freely and maintain power at higher speeds. This calibration delivers smoother acceleration, steady power delivery and a responsive feel whether cruising or pulling light loads.
Tailored Fit for 1968 to 1972 A Body Frame Clearance
These mid length headers are specifically shaped to clear the narrow frame rails of 1968 through 1972 A Body sedans and coupes without trimming or fabrication. Factory style flanges and included gaskets align precisely with LS head ports for a plug and play installation, avoiding interference with steering or suspension brackets. Installers save time and eliminate guesswork by using the supplied hardware and original mounting points. The result is a fully integrated exhaust solution that works seamlessly with the existing undercarriage layout.
Engineered for a precise fit and reliable performance on your 1968 to 1972 A Body with an LS engine.
