Designed specifically for LS swap applications, these headers are not compatible with 1999 and newer factory equipped GM trucks and SUVs and are not a direct bolt on replacement for factory exhaust manifolds or OEM Y pipe systems. These LS swap headers require custom installation and fabrication for proper exhaust routing. Compatible with 4.8L 5.3L 6.0L and 6.2L LS based V8 engines including LS1 LS2 LS3 and LS6 platforms. Suitable for headers for 5.3 LS engine conversions, 6.0 LS swap headers, LS engine conversion builds and other Gen III and Gen IV LS swap configurations. Not compatible with 2014 and newer LT based engines. Commonly used in S10 LS swap headers applications, C10 LS swap builds, K10 truck conversions, hot rod LS swaps, classic truck restorations and custom chassis builds where compact shorty LS headers are required to maintain steering shaft, frame and suspension clearance. The tight tuck layout supports installations where space is limited and block hugger LS headers are often considered. The black coated finish is designed to withstand repeated heat cycles while maintaining a muted non flashy appearance for stealth LS builds. Each set features 2.5 inch 3 bolt collectors compatible with standard LS swap exhaust systems and includes MLS multi layer steel header gaskets along with solid copper 2.5 inch collector gaskets for improved sealing durability compared to standard composite gasket sets. Designed for universal LS engine swap applications requiring custom installation. Designed for vehicles manufactured in 1967 and earlier prior to federal emissions standards. Not for use on any vehicle 1968 or newer or any engine originally manufactured with emissions equipment.
