Ceramic Coated 1-7/8in Mid-Length Headers for LS Engine Swaps
When installing an LS engine into a 1977 to 1990 GM B Body chassis these 1-7/8in ceramic coated mid length headers solve tight frame rail and floor pan clearance with precise exhaust routing. Mandrel bent steel primaries feed into a 1-7/8 inch collector and meet LS head bolt patterns with machined 3/8 inch flanges and included gaskets and bolts for a leakproof seal. The silver ceramic finish resists heat and corrosion under repeated cycles. Direct fit with MuscleRods engine mount kits may require minor pinchweld seam trimming at the firewall floor junction.
Precision Fitment for GM B Body Conversions
These LS 1-7/8 inch ceramic coated mid length headers are engineered for LS engine swaps in 1977 to 1990 GM B Body platforms. Each header is formed to clear frame rails and steering linkages specific to those models. When used with MuscleRods LS mount kits, engine and transmission alignment remain true to original geometry. This exact match preserves drivetrain angles and minimizes vibration, delivering a plug-and-play installation that cuts project time.
Optimized Flow for Peak Power
Featuring 1 7/8 inch primaries, these mid length headers balance low rpm torque and high rpm horsepower. The tube size pairs perfectly with LS exhaust port dimensions, promoting efficient pulse extraction and reducing backpressure. As a result, drivers experience a strong torque curve off idle and sustained breathing at red line, unlocking maximum output on street machines and track builds alike.
Robust Construction and Sealing
Each flange is machined to 3/8 inch thickness to maintain surface flatness under extreme heat cycles. This rigidity prevents warping and ensures a leak free joint without the need for repeated retorquing. Smooth, consistent weld beads eliminate stress points, providing long term durability even under heavy load. The precision flanges and quality gaskets guarantee a flawless seal from first fire to full throttle runs.
Heat Management and Endurance
The silver ceramic coat offers advanced resistance to heat and corrosion. By reflecting radiant energy, the finish lowers underhood temperatures, protecting wiring and intake parts from heat soak. The barrier also prevents rust through seasonal exposure, while maintaining its appearance through repeated thermal cycles. As these headers reach optimal operating temperature quickly, they deliver a deep, muscular exhaust tone that boosts overall performance across the rev range.
Backed by steel construction and a silver ceramic coat, these headers ensure durable, leakproof performance for your LS conversion.
