LS Engine Exhaust Header for Swap Installations
When retrofitting an LS mill into a classic GM pickup, reliable exhaust flow and durable hardware are essential to maintain performance and service life. This header assembly employs a mid length design with 1 7/8 inch primary tubes welded to a robust 3/8 inch thick flange for precise port alignment. Tubes are formed from 16 gauge steel and sealed under a silver ceramic coating that reflects radiant heat and resists corrosion. Fully compatible with LS engines and engineered to integrate with LS engine mount kits, it fits 1988 to 1998 two wheel drive GM trucks without modification. The kit includes high quality gaskets, mounting bolts and detailed instructions for a consistent seal and straightforward installation.
Performance Impact
The 1-7/8" mid-length header design optimizes exhaust flow, reducing back pressure and enhancing scavenging. This improved flow helps the LS engine achieve higher horsepower and torque by allowing more aggressive ignition timing. The reduced heat retention in the exhaust improves thermal management, which also supports a more aggressive exhaust tone by preventing heat soak from dulling throttle response and muffling sound output.
This 1 7/8 inch mid length header with silver ceramic coating delivers reliable performance and precise fitment for LS engine swaps in 1988 to 1998 two wheel drive GM trucks.
