1-7/8 Ceramic Coated Mid-Length LS Headers for A-Body
For LS engine swaps in 1973 to 1977 GM A Body frames, these 1.875 inch ceramic coated mid-length headers deliver precise exhaust routing and reliable sealing in tight engine bays. Stainless steel tubing and a silver ceramic coating reflect radiant heat away from hoses and wiring under the hood. Mandrel bends preserve a full 1.875 inch bore, while 3/8 inch thick flanges are CNC machined for consistent sealing. The kit includes gaskets, bolts and all hardware plus clear instructions for quick assembly. Rugged tubing and full fitment components ensure lasting performance through thermal cycles in classic A Body LS swaps.
Precision Fit for 1973–1977 GM A-Body Applications
These headers have been engineered specifically for LS engine swaps on 1973 to 1977 GM A-Body models, ensuring a direct bolt-in fit without the need for extensive modification. When paired with MuscleRods mounts, they maintain ideal engine placement and drivetrain angles to preserve driveshaft alignment and minimize vibration, delivering reliable performance and extending transmission life.
Optimized Flow with Ceramic Barrier Coating
Featuring 1-7/8" diameter primary tubes in a mid length design, these headers maximize exhaust scavenging and reduce backpressure to unlock improved torque across the RPM range. The silver ceramic finish acts as a thermal barrier, reflecting radiant heat back into the exhaust stream to lower under-hood temperatures and protect adjacent components from heat soak.
Durable Construction and Leak-Free Sealing
Manufactured from premium stainless steel, each flange is precision machined to a uniform 3/8" thickness for consistent flatness under heat cycles. This rigidity ensures flawless sealing against the cylinder head surface, preventing leaks and maintaining optimal exhaust flow. The inherent corrosion resistance of stainless steel guarantees long-term durability, even under harsh operating conditions.
Signature Muscle-Car Tone and Complete Installation Kit
The carefully tuned primary lengths and merge collector geometry produce an aggressive, deep muscle-car exhaust note without compromising responsiveness. A comprehensive kit is included, featuring high-quality gaskets and corrosion-resistant bolts sized for exact fitment. All hardware arrives pre-matched to component flanges, streamlining installation and ensuring reliable joint integrity from initial startup to track day demands.
These stainless steel ceramic coated mid length headers ensure precise fit, leak free sealing, and enduring durability for your 1973-1977 GM A Body LS swap.
