1978-1988 G-body 1-7/8in Ceramic Coated Long Tube Headers
Swapping an LS engine into your 1978-1988 G-body requires an exhaust solution that aligns perfectly and endures extreme heat loads. Featuring a 1.875 inch tube diameter, these ceramic coated long tube headers optimize exhaust flow and lower underhood temperatures. The durable mild steel construction and 3/8 inch flange deliver a leak free seal, while the precision fit design ensures straightforward installation with factory exhaust connections.
Precision Fitment for LS Engine Integration on 1978 to 1988 G body Vehicles
The CNC machined flange and bolt pattern are tailored to match LS cylinder heads, ensuring pinpoint alignment during installation. This precision fitment reduces the need for manifold spacers or exhaust tweaks, streamlining the swap process. By maintaining exact port to flange registration, exhaust pulses flow smoothly without turbulence or leaks. Technicians appreciate how this design minimizes clearance issues with steering shafts and factory crossmembers, making it easier to restore original chassis geometry.
Enhanced Exhaust Flow with 1.875 Inch Tubing
The full length 1.875 inch primary tubes balance gas velocity and volume to optimize scavenging across the RPM band. This diameter promotes a steady exhaust pulse rhythm, which translates into improved throttle response and torque at low to midrange engine speeds. Matching these headers to an LS engine's torque curve helps free up trapped exhaust energy and reduces back pressure. Enthusiasts will notice sharper acceleration and a more robust power curve on both street and strip.
Advanced Ceramic Coat for Underhood Temperature Control
The ceramic coating acts as a thermal barrier, reducing underhood temperatures by insulating the metal and reflecting radiant heat. Lower temperatures help protect nearby wiring harnesses, plastic components, and fuel lines from heat fatigue. Internally, retained heat keeps exhaust gases hotter, improving flow velocity as they exit the header primaries. This combination of external cooling and internal heat conservation contributes to extended header life and consistent performance over thousands of miles.
Durable Steel Construction with Leak Proof Header Flange
Premium mild steel tubing offers a blend of strength and ductility, allowing the headers to resist cracking under repeated heat cycles. The 3/8 inch thick flange provides a stable, flat mounting surface that resists warping and maintains a tight seal. When paired with robust V-band clamps and high-temperature gaskets, this flange design virtually eliminates exhaust leaks at the collector joint. Long lasting performance under high stress conditions means you can push your LS swap without worrying about header integrity.
