Stainless Steel Long Tube Headers for LS Swap C10, K10 & Square Body GM Trucks

Upgrade your classic GM truck LS swap with these Stainless Steel Long Tube Headers, engineered specifically for LS-series engine swap applications in compatible Chevrolet and GMC C/K-series trucks and square-body SUVs. Designed with real-world fitment and installation requirements in mind, the CAE-032 polished stainless steel header set uses proven geometry tested on actual vehicles and refined for reliable clearance in both 2WD and 4WD configurations.

Constructed from natural 304 stainless steel with a polished finish, these Stainless Steel Long Tube Headers combine durability, corrosion resistance, and performance-focused exhaust flow. The 1-3/4-inch mandrel-bent primary tubes maintain consistent diameter through the bends, while precision TIG welding and CNC-machined flanges provide accurate construction and dependable long-term performance.

The formed 3-inch merge collectors terminate without a flange, giving you greater flexibility when fabricating a custom exhaust system. Both headers feature integrated O2 sensor bungs, making them ready for compatible LS swap engine management and exhaust configurations.

This LS swap header kit also includes upgraded factory-style multi-layer steel header gaskets and a complete 12-piece header bolt set. Including both sealing and mounting hardware provides a more complete installation solution than header kits sold without gaskets or bolts.

Important Fitment Information

These Stainless Steel Long Tube Headers are not designed for every GM truck chassis or engine configuration. Verify your vehicle and engine combination before ordering.

• Not compatible with SBC engines

• Not compatible with BBC engines

• Not compatible with OBS/GMT400 chassis

• Not intended for Gen V LT engines

• Factory spark plug wires are not compatible with the header routing

• Factory spark plug heat shields are not compatible

• Quality aftermarket spark plug wires are recommended

Due to the specific routing of the headers, clearance and installation requirements can vary depending on the engine mounts, crossmember, drivetrain configuration, and other components used during the LS swap.

Recommended LS Swap Components

For the best fitment and clearance based on our test vehicle, Tejas Performance LS swap engine mounts and crossmembers are strongly recommended.

Before purchasing, customers should review the detailed fitment and clearance video included with the listing images. This provides a better understanding of the header routing, required clearances, and installation considerations for the intended LS swap application.

Why Choose 304 Stainless Steel Long Tube Headers?

304 stainless steel is widely used in performance exhaust applications because of its durability and resistance to corrosion. Combined with mandrel-bent primary tubes and TIG-welded construction, these Stainless Steel Long Tube Headers are designed to provide a durable exhaust solution for demanding LS swap projects.

The long tube design provides individual primary tubes that merge farther downstream, helping create an efficient exhaust path for LS-series engines. The 1-3/4-inch primary tube size and 3-inch merge collectors provide a performance-oriented configuration suitable for custom LS swap exhaust systems.

The polished finish also gives the engine bay a clean, high-performance appearance while maintaining the natural look of stainless steel.

• Left Stainless Steel Long Tube Header

• Right Stainless Steel Long Tube Header

• Multi-layer steel header gaskets

• Complete 12-piece header bolt set

LS Swap Installation Considerations

Before installing these LS swap headers, confirm that your engine, chassis, engine mounts, transmission configuration, steering components, spark plug wires, and exhaust system provide adequate clearance.

The collector ends are intentionally left without flanges, allowing the installer or exhaust shop to fabricate a custom exhaust connection based on the vehicle's specific configuration.

The integrated O2 sensor bungs on both headers provide convenient sensor locations for compatible LS engine management systems.
