LS Swap Header Replacement For 1960-1986 C10 And More

The LS Swap Header Replacement is designed for classic 1960–1986 C10, Camaro, GMC, and Silverado platforms that received an LS-based powerplant. With a 1 5/8 inch primary and a 2 1/2 inch collector, this shorty header emphasizes improved exhaust flow while keeping overall length compact for tight engine bays. Constructed from T304 stainless steel, the headers offer corrosion resistance and durability. The silver finish contributes to a clean, factory-like appearance under the hood.
2Pcs LS Swap Shorty Headers For Classic Trucks

This two-piece shorty header set is tuned for LS swaps in Chevy and GMC trucks from 1960–1986. The 1 5/8 inch primaries paired with a 2 1/2 inch collector improve exhaust scavenging without extending into narrow engine compartments. Made from durable T304 stainless steel and finished in silver, these headers are designed for longevity and corrosion resistance, offering a straightforward swap for many LS swap builds.
Shorty Headers for LS Swaps With Upgraded Gaskets

This shorty header set emphasizes compatibility across a wide range of LS engines, including LS1, LS2, LS3, LS6, LS7, and later Gen 3/4 platforms (1998–2020). The system is designed for maximum flow improvements over stock manifolds, translating to better horsepower, torque, and throttle response in street and swap applications. The universal fit makes it a versatile option for various LS swap scenarios, though LT-style engines (2014+) are not supported.
Stainless Steel LS Swap Long Tube Headers

Long tube headers typically deliver higher peak power by extending exhaust runners for improved scavenging. This replacement set is polished stainless steel and designed for 1960–1998 Silverado, C10, and Sierra variants with LS1–LS7 powerplants. The emphasis is on durability and a refined finish, suitable for long-term use in various weather conditions. While longer primaries may require more precise fitment planning, the potential performance gains are notable for dedicated LS swap builds.
AUTO MART Exhaust Header LS Conversion Swap

AUTO MART offers an exhaust header designed for LS conversions in C10, Camaro, GMC, and Silverado models, covering LS1 through LS9 variants and 4.8L–6.2L displacements. The headers use high-quality 304 stainless steel and incorporate a robust 7/16 inch steel plate head flange for added strength and a reliable seal. Welding quality is emphasized to reduce cracking and improve long-term reliability in demanding swap projects.
Polished LS Swap Headers For 1982–2005 Chevy C10 And Sonoma

These polished LS swap headers are crafted for 1982–2005 Chevrolet C10, S10-based Sonoma, and other LS-equipped V8 swaps. The stainless steel construction resists corrosion while delivering clean, polished aesthetics under the hood. They are intended for swaps where an LS engine is not originally installed from the factory, ensuring a proper fit within traditional engine bays and mounting points for a classic truck build.
Certified Automotive Experts Long Tube Headers For LS Swaps

Certified Automotive Experts offers long tube headers for LS swaps across 60s–87 Chevy and GMC trucks, with compatibility for 88 and newer 2WD square body vehicles (OBS not included). The headers are built from 304 stainless steel, featuring CNC-machined flanges and TIG-welded joints for a precise fit and durable performance. The mandrel-bent tubes are designed to maximize airflow, supporting higher horsepower potential in LS swap builds.
Buying Guide: Key Purchase Considerations
- Engine and vehicle compatibility: Verify whether the header system is designed for your exact LS engine family (LS1, LS2, LS3, LS6, LS7, etc.) and your truck year/model to ensure proper fitment and clearance.
- Header type and length: Shorty headers typically fit better in tight engine bays and reduce under-hood heat, while long tube headers may offer higher peak power at the expense of space and possibly more complex installation.
- Material and finish: Stainless steel (304/409) resists corrosion and is common in performance headers. Polished finishes look great but may require more maintenance to stay pristine.
- Gasket and flange construction: Gasket materials and flange thickness influence sealing reliability. Some kits include upgraded gaskets for improved sealing and longevity against cracking or leaks.
- Fitment notes and inclusions: Check for included hardware, mounting brackets, or upgraded gaskets. Some products specify compatibility limitations with LT engines or non-LS builds, which is crucial for swaps beyond traditional LS configurations.
- Durability and warranty: Consider headers with robust welding and reinforced flanges, especially for off-road or rough-road usage. A warranty can provide peace of mind for long-term ownership.
- Performance expectations: Shorty headers generally improve mid-range torque and throttle response, while long tubes can push higher horsepower in optimized swapped engines. Review the dyno results or supplier claims in context with your build goals.
- Installation complexity: Installation difficulty varies by header design and vehicle year. Some may require additional clearancing, sealing, or exhaust system modifications to achieve best fit and performance.
- Emissions and legal considerations: Depending on location and vehicle usage, some header setups may affect local emissions requirements. Confirm with local regulations if necessary.
