- Complete Upgrade Kit – Includes multi-layer steel (MLS) gaskets and header bolts for a superior seal, reduced leaks, and faster installation compared to standard fiber gasket kits.
- Proven Fitment – Designed for LS swap applications in 1973–1987 Chevy/GMC C/K10–30 2WD & 4WD pickups and 1988–1991 square-body C3500/K3500, Blazer, Jimmy, and Suburban models. (Not for 1988–1998 OBS/GMT400 or 2014+ Gen-V LT engines.)
- High-Performance Flow Design – Long-tube configuration with 1-3/4” mandrel-bent primaries and 3” merge collectors increases exhaust scavenging, torque, and horsepower across the powerband.
- Heavy-Duty Construction – Built from thick-wall steel tubing with CNC-machined 3/8” flanges and precision TIG-welded joints to prevent warping, leaks, and early failure.
- Thermal Barrier Coating – Black aluminized finish resists corrosion and acts as a true heat shield, lowering under-hood temperatures while providing a clean, stealth appearance.
- Engine Compatibility – Works with 4.8L, 5.3L, 5.7L (LS1), 6.0L, and 6.2L LS-series engines. Not designed for factory LS or SBC/BBC engines.
- Installation Ready – Includes O₂ sensor ports and is compatible with both 2WD and 4WD chassis. When using large-case transmissions (TH400 or 4L80E), minor bellhousing ear trimming may be required.
