Exhaust Header VS Manifold, which is the better choice?
The structural differences between exhaust headers and manifolds lie in the material and size. Exhaust headers, like the Flashark Exhaust Header for 1977-1983 Nissan Datsun 280Z 280ZX 2.8L, are made from lightweight, thinner stainless steel, while manifolds are typically made from thicker iron. Headers are also longer, and unlike manifolds, they reduce back pressure, improving performance. With individual tubes for each cylinder, exhaust headers allow exhaust gases to exit freely, enhancing horsepower and engine efficiency.
Upgrading your 280Z headers is essential for better engine performance and sound. Whether you're on the road or track, Flashark headers provide more power and a richer exhaust note. With a direct bolt-on design, installation is easy—no modifications needed!

Q1: Will this header fit both the Datsun 280Z and 280ZX models?
A1: Yes, this performance 280z header is specifically designed for the 1977-1983 Nissan Datsun 280Z and 280ZX models equipped with the 2.8L L28 engine. It provides a precision fit for the chassis requirements of both the S30 and S130 platforms within those production years.
Q2: How much horsepower can I expect from these L28 headers?
A2: Installing our L28 headers typically yields a power increase of 10-15 horsepower and a significant bump in mid-range torque. By replacing the restrictive factory 280zx exhaust manifold with our high-flow long-tube design, you optimize exhaust scavenging for better engine efficiency.
Q3: Is this a direct bolt-on replacement for the stock 280zx exhaust manifold?
A3: Yes, these headers are designed as a direct replacement. They utilize the factory mounting points on the L28 cylinder head. While it is a bolt-on part, we recommend professional installation to ensure a perfect seal with your existing 280zx exhaust system.
Q4: What material is used for the Flashark 280z headers?
A4: Our 280z headers are constructed from high-grade T304 stainless steel with mandrel-bent tubing. This ensures maximum durability against corrosion and heat cycling, unlike cheaper mild steel alternatives that tend to rust and crack over time.
Q5: How will this upgrade affect my Datsun 280zx exhaust sound?
A5: Upgrading to this header will give your 280zx exhaust a much deeper, more aggressive "straight-six" growl. The tuned-length runners eliminate the muffled tone of the stock manifold, providing a crisp and sporty sound that Datsun enthusiasts love.
Q6: Does this header accommodate the factory fuel injection system on the 2.8L engine?
A6: Absolutely. Since the 1977-1983 Datsun 280Z and 280ZX are fuel-injected, our header is designed with the necessary clearances for the intake manifold and fuel rail components common on the L28E and L28ET engines.
Q7: Are gaskets and hardware included with the header for 1977-1983 Nissan Datsun?
A7: Yes, each kit includes high-quality manifold gaskets and the necessary hardware required for installation. We provide everything needed to swap out your old 280z exhaust manifold for our performance stainless steel version.
Q8: Can I use this header on a 280ZX Turbo model?
A8: This specific header is designed for Naturally Aspirated (NA) L28 engines. If you are looking to replace a 280zx exhaust manifold on a Turbo model, modifications would be required to mount the turbocharger, as this is a traditional long-tube atmospheric header.
Q9: What are the benefits of the long-tube design for the L-series engine?
A9: The long-tube design of these 280zx headers improves exhaust gas velocity. By having longer primary tubes, the exhaust pulses are timed to help pull the next cylinder's gases out (scavenging), which is the most effective way to gain power on the Datsun L28 engine.
Q10: Does this header provide clearance for the power steering and steering shaft?
A10: Yes, we have engineered these 280z headers to clear the steering shaft and most aftermarket power steering conversions. The compact yet efficient routing ensures there is no interference with critical steering components.
Q11: How do I maintain the polished finish of my new 280zx header?
A11: To keep your 280zx header looking its best, we recommend wiping it down with isopropyl alcohol before the first start-up to remove any oils. Over time, the stainless steel will naturally turn a beautiful golden/blue hue due to the heat—a hallmark of high-quality T304 steel.
Q12: Will this header improve my fuel economy?
A12: While most owners buy 280z headers for performance, the improved engine breathing can lead to better fuel efficiency under normal cruising conditions. By reducing the "pumping losses" of the engine, it doesn't have to work as hard to expel exhaust gases.
Q13: Is Flashark's 280z header "but not that expensive" compared to others?
A13: Exactly. Flashark specializes in providing professional-grade performance parts that are but not that expensive. We offer the same T304 quality and mandrel-bending technology as high-end boutique brands but at a price point that makes Datsun restoration accessible.
Q14: Does it fit the earlier 240Z or 260Z models?
A14: While the L-series cylinder heads are similar, this specific model is optimized for the 1977-1983 2.8L port shape and chassis clearance. For the best results on a 240Z or 260Z, we recommend checking our specific listings for those earlier years to ensure perfect alignment with the exhaust system.
Q15: Why is mandrel-bending important for my 280zx exhaust system?
A15: Mandrel bending ensures that the pipe diameter remains constant through every curve. Unlike "crush" bending used in cheap 280zx exhaust manifold replacements, mandrel bending prevents restrictions, allowing your L28 engine to reach its full performance potential.
