LS Ceramic Coated Long Tube Headers for 1988-1998 Chevy C/K & GMC Sierra 2WD Trucks
When fitting an LS powerplant into a classic 1988 to 1998 Chevy or GMC two wheel drive truck, securing a set of ceramic coated long tube headers is critical to clear brake lines and steering components without compromise. These 1.875 inch primaries are mandrel bent to follow factory frame rails and seal directly to LS cylinder head ports without the need for spacers or adapter plates, preserving a tight exhaust path from startup. A ceramic barrier coating retains radiant heat within the exhaust stream, lowering underhood temperatures and guarding intake runners, wiring harnesses and brake hoses. A sturdy V band collector clamp provides a leak free junction for reliable performance under high exhaust pressure while thick mild steel flanges maintain a consistent seal through repeated heat cycles.
Precision Tube Routing for Seamless LS Integration
The 1.875 inch primary tubes are mandrel bent to follow the contour of the factory frame rails and seal directly to LS cylinder head ports without spacers or adapter plates. This exact fit ensures ample clearance around brake hard lines and steering components, eliminating the need for modifications that can introduce fitment issues. The precision mating to head port surfaces reduces the potential for exhaust leaks at startup and maintains uniform exhaust velocity from the moment the engine fires. By streamlining the installation process, this header set saves valuable build time and ensures consistent performance across applications.
Ceramic Barrier Coating for Effective Thermal Management
A robust ceramic coating forms a barrier that reflects radiant heat back into the exhaust stream, reducing underhood temperatures by up to fifty percent compared to bare steel. Lower bay heat helps preserve intake runner efficiency, protect wiring harness integrity and guard brake hoses from heat degradation. The inert finish resists oxidation and stands up to repeated heat cycles without flaking, ensuring long term durability. Maintaining optimal bay temperatures also supports consistent air charge density and reliable engine performance in demanding conditions.
Heavy Steel Flanges and V band Collector Connection
Each flange is made from three eighth inch thick mild steel that retains flatness under high exhaust pressure, preventing warping and sealing evenly against the head surface. The V band collector clamp provides a secure yet service friendly connection, permitting quick disassembly for maintenance or upgrades without compromising the seal. Robust wall thickness in the primary tubes withstands the thermal expansion and vibration common to truck use, while the V band joint mediates stress at the merge point. Together these features deliver a tight seal and reliable exhaust flow over countless heat cycles and highway miles.
