Exhaust Headers 1-5/8 in. Stainless Steel Polished Finish
Best for: Ford F-150 5.4L V8 owners seeking a direct bolt-on upgrade with minimal fitment concerns. These headers replace stock manifolds and rely on fully mandrel-bent 16-gauge 304 stainless steel tubes to improve mid-range horsepower. The polished finish adds corrosion resistance and a clean look under the hood. This option suits a stock-to-m mildly boosted daily driver aiming for noticeable throttle response gains from idle to mid RPMs.
Why chosen: Direct replacement fit reduces installation time and avoids custom fabrication. The stainless construction supports durability in daily driving and moderate performance builds. The design focuses on maximizing efficiency across the most-used RPM range for street use.
Caution: Ensure compatibility with your specific exhaust piping and check clearance around the steering linkage and shock towers on certain F-150 configurations.
Stainless Steel LS Swap Long Tube Header Replacement
Best for: GM Silverado owners performing an LS engine swap who want a full-length long-tube header for improved exhaust scavenging. The polished finish helps resist corrosion and maintain a clean engine bay appearance. This header is designed for LS1/LS2/LS3 families and related configurations, making it a solid choice for swap-focused builds seeking efficiency gains across mid- to high RPMs.
Why chosen: The long-tube approach and full-length design support smoother exhaust flow, especially when paired with compatible high-flow manifolds and cat-back exhausts. It’s a straightforward upgrade for LS swapped trucks that prioritize power delivery and engine breathing.
Caution: Not intended for non-LS factory Ford engines; verify engine and exhaust matching before purchase.
LS Swap Long Tube Headers for 1979-2004 Mustang Fox Body & SN95
Best for: Mustang builds that use GM LS engine swaps and seek high-flow capability. With 1-7/8” primaries and a 3” collector, this stainless steel kit targets players who want robust horsepower gains across the powerband while preserving engine breathing in boosted or naturally aspirated configurations.
Why chosen: The design emphasizes LS compatibility in classic Mustangs, offering a balance of hardware fit, flow, and durability. The 304 stainless construction supports long-term performance in performance-focused street or weekend-warrior applications.
Caution: Not designed for factory Ford engines; ensure your swap configuration aligns with the stated vehicle scope and mounting points.
Long Tube Headers for 73–87 C10/K10 and 88–91 Square-Body
Best for: Classic GM pickups and square-body enthusiasts performing an LS swap or upgrading exhaust flow in mid- to late-1980s platforms. The kit includes multi-layer steel (MLS) gaskets and header bolts for a superior seal and easier installation compared with standard fiber gaskets.
Why chosen: The long-tube layout improves exhaust scavenging, which can translate to torque gains in older engines when paired with proper intake and exhaust systems. The coating and gasket kit contribute to reliability in daily drivability and performance builds.
Caution: Not compatible with 1988–1998 OBS/GMT400 or 2014+ Gen-V LT engines; verify model year and platform before purchase.
Long Tube Headers Replacement For AP02 LS Swap
Best for: Silverado/Sierra enthusiasts undertaking an LS swap with broad model-year coverage (1960–1998). It provides compatibility across several LS variants and emphasizes an efficient path to higher horsepower through improved exhaust flow.
Why chosen: The design supports broad GM truck compatibility and emphasizes long-tube benefits for LS-powered swaps, delivering improved breathing in naturally aspirated or boosted builds.
Caution: Verify that your exact truck year and LS variant are compatible with this header kit to avoid fitment issues.
Buying Guide: Long Tube Headers For 4.6 2V And LS-Swap Builds
- Engine compatibility: Identify whether the header is designed for Ford 4.6 2V applications or GM-LS swap configurations. LS-specific headers often require swap-related fitment considerations.
- Tube diameter and primaries: Larger primaries (1-7/8″ to 1-5/8″) improve high-RPM flow but may require more clearance. Match primaries to your power goals and engine setup.
- Material and finish: Stainless steel resists corrosion and handles heat well; aluminized or coated options can save cost but may wear differently under heavy use. Choose corrosion resistance that fits your climate.
- Gaskets and hardware: MLS gaskets and high-grade header bolts reduce leaks and simplify installation. Check if a complete kit is included or if you need to source gaskets separately.
- Fitment and clearance: Verify clearance around the engine bay, steering linkage, and suspension components. Long-tube designs may require additional exhaust adjustments or cross-member clearance.
- Installation complexity: Some headers are direct bolt-ons; others demand additional fabrication, exhaust modification, or tuning to maximize gains. Budget time for installation planning.
- Performance expectations: Expect improved scavenging, better throttle response, and potential horsepower gains, especially in mid to high RPM ranges. Gains depend on the entire exhaust system and intake configuration.
- Durability and warranty: Consider the coating quality and the reputation of the brand for long-term reliability, especially in harsh climates or daily-driver conditions.
Frequently Asked Questions
- Do long tube headers fit stock engines? Yes, many are designed for direct bolt-on installation on compatible engine platforms, but verify fitment for your model year and engine size.
- Will headers improve my horsepower? They can improve power by improving exhaust flow, particularly in mid- to high RPM ranges, when paired with appropriate exhaust and intake components.
- Are stainless headers worth it? Stainless steel offers corrosion resistance and durability, which can extend service life in harsh environments and maintain a polished appearance.
- Do I need tune after installing headers? Some setups benefit from a tune to optimize air-fuel ratios and ignition timing, but not all installations require it. Check your combination and local regulations.
- What should I consider for LS swap headers? LS swap headers generally require LS-specific fitment and may differ from factory Ford exhausts. Confirm engine variant compatibility and mounting points.
- Is gasket kit included with headers? Some kits include MLS gaskets; others require separate purchases. Review product details for gasket inclusion.
