Upgrade your custom LS engine swap with these 304 stainless steel shorty headers, designed for Gen 3 and Gen 4 LS-based engines. Featuring 1 5/8-inch mandrel-bent runners, CNC-cut flanges, and TIG-welded seams, they are built to support exhaust flow and provide clearance around steering and suspension components.
The V-band collector design creates a gasket-free, metal-to-metal connection for exhaust fabrication. Each set includes factory-style Multi-Layer Steel (MLS) gaskets and LS-specification M8 × 1.25 × 25 mm header bolts for a suitable installation setup.
These headers are intended for custom LS engine swaps only and are not designed for vehicles originally equipped with LS engines from the factory. They can be used in swap projects involving classic GM vehicles such as the C10, K10, S10, and Chevelle, subject to the specific vehicle and installation requirements.
