LS Swap Header Replacement for 1960-1986 Chevy C10 … 1 5/8″ / 2 1/2″
These shorty headers are designed for classic C10 and G-Body swaps into LS engines. The 1 5/8″ primary tubes with a 2 1/2″ collector aim to improve exhaust flow over stock manifolds, while stainless construction adds corrosion resistance for longevity in daily driver or weekend warrior builds.
Shorty Headers for LS Swaps – 304 Stainless Steel
These shorty headers are tailored for LS swap projects across classic trucks and SUVs. They accommodate a broad range of LS engines (4.8L–6.2L) and various Gen 3/4 configurations. The design emphasizes improved flow and throttle response while remaining compatible with swap-specific needs. Not intended for LT or LT-based engines.
Stainless Steel LS Swap Long Tube Header Replacement
This long-tube option provides maximum flow for LS swaps in full-size pickups and C10s. The polished finish adds a refined look under the hood, and the header is designed to replace factory pieces with a focus on improved horsepower and torque across a broad RPM range. Built for LS1–LS7 variants.
AUTO MART Exhaust Header LS Conversion Swap
Designed for Chevy C10 and other G-Body swaps, these headers use 304 stainless steel with a strong head flange and robust welding. The kit emphasizes durability in high-heat conditions and aims to provide a reliable seal during long-term LS engine operation. Suitable for a range of 4.8L–6.2L engines and swap projects.
2Pcs LS Swap Shorty Headers Stainless Steel Silver
The dual shorty header set mirrors other shorty options with 1 5/8″ primaries and a 2 1/2″ collector. Stainless construction offers corrosion resistance and a silver finish. This option is well-suited for swaps that prioritize fitment in tight engine bays or retrofits where ground clearance is a concern.
Buying Guide: Key Considerations For G-Body LS Swap Headers
- Header Type: Shorty vs. long-tube designs impact ground clearance, cost, and torque in different RPM ranges. Shorties typically fit tighter engine bays and may be easier to install, while long tubes maximize top-end power.
- Material And Finish: Stainless steel (304) resists rust better than aluminized steel and supports longevity in varied climates. A polished finish not only looks good but may simplify cleaning and maintenance.
- Fitment And Applications: Confirm compatibility with your specific G-Body model, year, and LS engine variant (LS1, LS2, LS3, etc.). Some headers require minor clearancing or adapters for a proper seal with factory exhaust manifolds or swap components.
- Welding And Flange Quality: Durable welds and a robust head flange (often 7/16″ or larger) help reduce cracking and leaks under heat and vibration typical of engine swaps.
- Gasket and Hardware Compatibility: Some sets include upgraded gaskets and mounting hardware. Verify whether you need additional gaskets or hardware based on your exhaust system and engine mounting.
- Emission Regulations: Ensure chosen headers comply with local emissions rules if required by your build location or use. Some swaps may require additional components for legal certification.
- Installation Considerations: Factor in manual or professional installation time, vehicle weight distribution, and potential need for exhaust routing changes or aftermarket mid-pipes.
- Performance Goals: Decide whether your priority lies in daily drivability, track readiness, or a balanced street setup. Matching headers to a suitable exhaust, cam, and intake can optimize results.
- Budget And Warranty: Compare price points across brands and consider warranty coverage for typical heat cycling and installation wear.
- Maintenance: Stainless steel headers resist corrosion and are easier to clean, while coatings may require specific care to maintain appearance and performance.
