1-7/8 Ceramic Coated LS Mid-Length Exhaust Headers
Swapping an LS engine into a 1968 through 1972 A-Body chassis demands exhaust headers that route flawlessly around frame rails and suspension, and these 1 7/8 inch ceramic coated mid-length headers are engineered to fit without modifications. Each mandrel bent primary tube follows the factory contours to maintain ground clearance while the silver ceramic finish traps heat within the runners, cutting underhood temperatures and preserving wiring and hoses. Machined 3/8 inch flanges match LS head bolt patterns for a reliable seal and simplify installation by eliminating shims or spacers. Installers will value a bolt in solution built for both daily driving and spirited track use.
Mandrel Bent Alignment for 1968 to 1972 A Body Chassis
The mid-length tubes are mandrel bent from steel to closely follow the original frame rails and suspension geometry found on 1968 to 1972 A Body models. This bending process maintains a consistent inner diameter along each curve to prevent restrictions and sustain a smooth exhaust pulse, translating into more torque at lower engine speeds. By matching factory contours, these headers clear crossmembers and steering linkages without the need for notches or trimming to the floor. Installers will appreciate the ease of fitment that eliminates fabrication and speeds up the swap process. All tubes converge into a common collector designed to optimize scavenging, boosting throttle response during spirited acceleration.
Robust Steel Tube Architecture for Longevity
Constructed of durable steel, the header primaries resist cracking and fatigue from continual thermal cycling under demanding driving conditions. The uniform wall thickness balances weight and strength to endure daily commutes as well as high load events on the track. Precision welding at each junction reinforces critical high stress zones and provides consistent heat distribution to avoid hot spots that can lead to material failure. This steel framework also tolerates exposure to road debris and undercar corrosion, ensuring a reliable service life. Drivers benefit from a component that stands up to decades of use without warping or distortion.
Silver Ceramic Shell Enhancing Thermal Efficiency
A reflective ceramic coating forms a thermal barrier that locks exhaust heat inside the tubes, lowering the temperature beneath the hood by up to 100 degrees Fahrenheit. This controlled heat containment safeguards nearby electrical harnesses, hoses and intake components from premature aging. In addition, the preserved heat energy helps maintain exhaust gas velocity, improving catalytic converter performance and throttle pick up right off idle. The coating resists chipping and abrasive buildup, preserving the bright finish in harsh environments and simplifying cleanup after extended use. Overall this surface treatment plays a key role in consistent performance and component protection.
Precision Machined Flange Geometry for Consistent Sealing
Each flange is milled to a precise three eighths inch thickness to ensure flatness and eliminate distortion under high exhaust backpressure. CNC machining matches the LS head bolt pattern exactly, removing any need for shims or spacers during assembly. The increased flange mass dampens vibration and maintains gasket compression evenly across all ports, guaranteeing a seal that resists leaks even after repeated heating cycles. Bolts align effortlessly in the correct position, reducing installation time and the risk of exhaust blowouts. This meticulous attention to sealing geometry ensures robust operation on both daily drives and competition runs.
A precision fit that ensures consistent performance in every LS engine swap and builds lasting confidence under demanding conditions.
