Stainless Steel LS Swap Long Tube Header Replacement for Chevy Silverado
This long tube header is a full-length replacement designed for Chevy Silverado models with LS swaps. The polished finish emphasizes corrosion resistance and a clean installation. It targets LS1/LS2/LS3/LS6/LS7 configurations within 1960–1998 trucks, making it a straightforward choice for classic square-body retros or modernized rigs. Best for owners seeking a visually polished, durable header with broad compatibility in older GM platforms.
Best for: Silverado/GM trucks performing LS swaps who want a proven long-tube path with a showroom finish. Choose this if you value a finished look and robust steel construction. Limitation: Confirmation of exact manifold compatibility with your exhaust routing is advised to avoid clearance issues.
Ceramic Coated LS Swap Long Tube Headers for 1973–1987 C10/K10 Square Body
These ceramic-coated long-tube headers are engineered for LS swaps in classic square-body trucks. The coating helps manage heat, protect nearby components, and maintain performance under sustained loads typical of towing and daily driving. The design uses 1-3/4 inch primary tubes and a 3-inch merge collector to improve scavenging and torque. This product is well-suited for square-body frame layouts that require heat control and reliable street-performance.
Best for: Square-body enthusiasts who want heat management and proven LS swap fitment. Better for: those who tow or operate a hot-rodded daily driver. Caution: Ceramic coating benefits require proper curing and maintenance to prevent coating damage during handling.
Long Tube Headers Replacement For AP02 LS Swap (60-98 Silverado)
Designed for widespread Silverado/Sierra AP02 LS swap projects, this header supports LS1/LS2/LS3/LS6/LS7 variants. It features a long-tube design to improve exhaust flow, potentially boosting airflow and engine response. It is best for builders working on 1960–1998 GM trucks who want a flexible, widely compatible long-tube option.
Best for: Silverado/Sierra builders pursuing broad LS swap compatibility. Better for: projects where flexible engine variant pairing matters. Caution: Verify exact chassis clearance and mounting points with your specific cab/bed configuration.
Stainless Headers Replacement For Small Block Chevy GMC Trucks 1966–1987
This stainless steel header replacement is designed for classic GM trucks with small-block engines. It covers a broad range of models from 1966 to 1987, offering a durable option for those maintaining or restoring older trucks with carbureted or early fuel-injected setups. It can be a practical choice when LS swap isn’t the goal, but a robust exhaust upgrade is desired.
Best for: classic GM trucks needing durable headers without LS-specific complexity. Better for: builders focusing on small-block powertrains. Limitation: Not optimized for LS swaps or modern LS engine manifolds; fitment depends on your small-block configuration.
LS Swap Long Tube Headers For Ford Mustang Fox Body SN95
This LS swap long-tube set is tailored for Mustang Fox Body and SN95 platforms. It uses 1-7/8 inch primary tubes and a 3 inch collector to maximize scavenging in LS-based Mustang swaps. It is best for builders prioritizing Mustang-specific chassis clearance and a dedicated LS swap path. A caution is that it is not designed for factory Ford engines and may require additional mounts or clearances in some builds.
Best for: LS swap Mustangs needing a purpose-built long-tube path. Better for: street/strip builds that want maximum airflow in a dedicated chassis. Caution: Not a direct factory-fit for non-LS Mustang engines; verify compatibility with your engine and trans setup.
Buying Guide
What should you consider when choosing long tube headers for a 5.3 LS swap?
- Compatibility: Confirm engine variant (LS1/LS2/LS3/LS6/LS7) and vehicle model year to ensure fitment.
- Tube diameter and design: 1-3/4 inch to 1-7/8 inch primaries are common; larger primaries suit higher horsepower builds but require chassis clearance checks.
- Material and coating: Stainless steel resists corrosion; ceramic coatings help with heat management but may require maintenance and careful installation.
- Heat management: Ceramic coatings and heat shields protect nearby components in tight engine bays or towing scenarios.
- Clearance and fit: Ensure header-to-frame, steering, and exhaust routing do not conflict with accessories or suspension components.
- Intended use: Daily driving vs. track use, towing, or performance-focused applications influence choice between shorty vs. long-tube and coating options.
FAQ
- Are long tube headers necessary for an LS swap? They improve exhaust flow and scavenging, but the necessity depends on your goals, budget, and vehicle clearance.
- Can I install long tube headers on a Silverado with a factory manifolds? Yes, many long-tube options are designed as replacement upgrades, but verify mounting points and clearance.
- Will ceramic coating last on a daily driver? Yes, when properly installed and cured, it provides heat management and corrosion resistance in typical driving conditions.
- Do headers affect engine sensors or ECU tuning? Some setups may require minor tuning adjustments for optimal air-fuel balance and timing, but this varies by build.
- Is a specific brand essential for LS swap headers? Brand quality matters for fit, coating, and durability, but the selection should match your vehicle and engine variant.
- Can headers cause clearance issues with the steering rack or suspension? Yes, especially on tight chassis like Fox Body Mustangs; check primary tube routing and mounting locations.
