LS Swap Long Tube Headers for Fox Body and SN95
Brand: Certified Automotive Experts
Designed specifically for GM LS engine swaps in 1979–2004 Ford Mustang Fox Body and SN95 platforms. Compatible with popular LS engines such as 4.8L, 5.3L, 5.7L LS1, 6.0L LS2/LQ4/LQ9, and 6.2L LS3/L92. Not for factory Ford engines. The 1-7/8″ mandrel-bent primaries help maintain smooth airflow through bends, supporting improved engine breathing and potential horsepower gains. The 3″ collector aids exhaust scavenging, which can enhance mid-to-high RPM performance. Best for LS-swap projects that prioritize flow and durability. Caution: Confirm compatibility with your specific engine and subframe setup before purchase.
FAPO Turbo Headers For F BODY LS Platforms
Brand: FAPO
Compatibility covers Camaro 1998-2019, Corvette 1998-2019, Cadillac CTS 2004-2013, Pontiac Firebird 1998-2002, and GTO 2004-2006 with LS1/LS2/LSX/LS9/LQ9. Features a 1-3/4″ primary diameter, 2-1/2″ collector, and a heavy-duty 3/8″ head flange with 16-gauge thickness walls for strength and heat resistance. This design emphasizes low-to-mid RPM power delivery and a leak-free seal thanks to a full-mandrel 304 stainless steel tube and a hydraulically pressed flange. Best for LS-powered F Bodies that want improved throttle response and integrated turbo applications. Caution: Not all late-model F Body trims or generation swaps will accommodate this exact flange and collector setup; verify engine bay clearance and exhaust routing.
Long Tube Headers For LS Swaps (Black Coated) For Classic Trucks
Brand: Certified Automotive Experts
Includes 1-3/4″ mandrel-bent primaries and 3″ merge collectors designed for LS swap applications in 1973–1987 Chevy/GMC C/K trucks and 1988–1991 square-body models. Aimed at LS swaps, it provides a durable 16-gauge stainless-like feel with a robust finish and a careful fit for classic trucks. Best for LS-swapped square-body builds where pipe routing and collector spacing matter. Caution: Primaries and routing may not fit non-square body configurations without modifications.
Polished Stainless Steel Long Tube Headers For SBC 1973–1987
Brand: Certified Automotive Experts
Designed for Gen 1 SBC engines in 1973–1987 Chevy/GMC trucks and Blazer/Jimmy lines. Features polished stainless steel, full-length mandrel-bent tubes, and a 5/16″ head flange with hydraulic flattening for a leak-free seal. Best for classic small-block swaps where a high-quality finish and strong mid-to-high RPM performance are preferred. Caution: Not a direct LS swap header; ensure compatibility with your SBC engine and vehicle platform.
Certified Automotive Experts Long Tube Headers For LS Swaps
Brand: Certified Automotive Experts
Premium 304 stainless steel, CNC-machined flanges with TIG-welded joints, and mandrel-bent tubes for an optimal flow path. Designed for LS swaps in 1960–1987 Chevy & GMC trucks (C10/C20/C30) 2WD and later square body applications. Best for LS swap builders needing robust, corrosion-resistant headers with precise fitment. Caution: Not designed for OBS body styles or certain 1988–1998 GMT400 platforms.

Buying Guide: Key Considerations For F-Body Long Tube Headers
What engine and platform are you swapping? For Fox Body Mustangs and SN95s, ensure the headers fit the engine bay, chassis, and exhaust routing. LS-swapped F-Body configurations benefit from primary tube sizing, collector length, and flange design to optimize scavenging without interfering with engine mounts or steering. Consider these factors when choosing headers:
- Fitment: Confirm vehicle year, body style, and engine (LS vs. SBC) to avoid clearance issues with steering, frame rails, and subframe connectors.
- Primary Diameter: Larger primaries (1-7/8″ to 1-3/4″) typically boost power at higher RPMs but may affect low-end torque. Choose based on your power goals.
- Collectors: 2-1/2″ or 3″ collectors influence scavenging and peak power. Long-tube designs with larger collectors often favor high RPM performance.
- Material and Finish: Stainless steel offers corrosion resistance and longevity; aluminized or polished finishes vary by cost and appearance.
- Gaskets and Hardware: MLS gaskets and robust header bolts reduce leaks and simplify installation; verify included components.
- Installation: Some headers require aftermarket or additional modifications (starter clearance, steering box, or exhaust routing).

- Choose this if you want a robust LS swap in classic trucks as a cross-reference: Long Tube Headers For LS Swaps (Black Aluminized) — versatile LS swap fitment with MLS gaskets.
- Avoid this if you need a pure Fox Body SBC path: Polished SBC Long Tube Headers — designed for Gen 1 SBC engines, not a direct LS swap.
- Consider this for durable LS swap in square-body or early trucks: Certified Automotive Experts Long Tube Headers For LS Swaps — premium materials and precise fitment for LS swaps in classic trucks.
FAQ: Common Buyer Questions
- Q: Are these headers compatible with all LS engines in a Fox Body? A: Compatibility depends on the exact engine bay, mounting points, and exhaust routing. Check the listing for supported LS variants and verify with your installation plan.
- Q: Do headers require new gaskets or hardware? A: Some kits include MLS gaskets and header bolts, but confirm what’s included before purchase and plan for replacement gaskets as needed.
- Q: Will these headers affect exhaust clearance with a aftermarket exhaust system? A: Yes, long-tube headers alter pipe routing and may require adjustments or a custom exhaust; ensure your system aligns with the collector and pipe geometry.
- Q: Can I install these without professional help? A: Some installations are straightforward, but many LS-swap headers require engine/transmission clearance checks and possible subframe adjustments; weigh the complexity against experience.
- Q: Which header is best for daily driving versus track use? A: For daily driving with better low-end response, choose headers with balanced primary sizing and a sensible collector length. For high RPM track use, larger primaries with efficient scavenging typically perform best.
