1971-1976 B-Body LT Series 1-7/8 Ceramic Coated Long Tube Headers

1-7/8-inch Ceramic Coated Long Tube Headers for 1971-1976 B-Body

Fitting an LT powerplant into a 1971 to 1976 B-Body demands an exhaust header that balances precise fit with unrestricted flow. These 1 7/8 inch ceramic coated long tube headers are engineered for LT engine swaps and feature robust 3/8 inch flanges that ensure a leak-free seal. Installation hardware, including V band clamps and gaskets, is supplied to simplify setup and maintain tidy engine bay packaging.

Advanced Ceramic Coating for Heat Control

The ceramic layer on these long tube headers serves a dual purpose by reflecting radiant heat back into the exhaust stream and reducing underhood temperatures. This coating is applied in multiple even layers to create a hard shell that resists chipping and abrasion, maintaining its integrity over repeated thermal cycles. By keeping more heat in the exhaust, the design also supports improved scavenging and prevents excessive heat soak into nearby components. The result is consistent performance and reduced risk of heat-related damage throughout the powerband.

Precision Fitment Ensures Reliable Seal

Each header is CNC formed and equipped with 3/8 inch thick flanges that match factory exhaust ports exactly, eliminating misalignment and ensuring uniform contact. When paired with the supplied V band clamp, composite gaskets, and high grade bolts, this precise fit translates into a leak resistant joint that will remain tight under vibration and thermal expansion. Installers appreciate how these features simplify torquing procedures and reduce the need for retightening after initial break-in. The outcome is a worry-free seal that holds even under spirited driving.

Mild Steel Construction for Durable Performance

Fabricated from premium mild steel, these headers balance strength and formability to withstand the rigors of high heat and pressure. The material choice absorbs and dissipates stress without cracking, while the tubular design optimizes flow by minimizing surface disruptions. Welds are executed with a MIG process to produce smooth, consistent beads that resist fatigue over time. Combined, these factors deliver a robust assembly capable of enduring frequent use and the harsh conditions of track or street applications.

Engineered for a precise fit and reliable performance in your LT swap project.
