Exhaust Header VS Manifold, which is the better choice?
The structural differences between exhaust headers and manifolds are the material and size. From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.
Replacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. FLASHARK offers many products to help you create your own custom engine headers. It's really easy and convenient to use: direct bolt-on, no modification needed.
Fitment & Compatibility
| Brand | Model | Year Range | Full Compatible Specs |
|---|---|---|---|
| Chevrolet | Camaro | 1970-1981 | Factory-Equipped Small Block Chevy (SBC) 267-400 V8 Engine |
Q1: Will this FLASHARK exhaust header fit my 1970-1981 Camaro with a Small Block Chevy (SBC) V8?
A1: Yes, this exhaust header is specifically engineered for 1970-1975 and 1981 Camaro models equipped with a Small Block Chevy (SBC) V8 engine, ranging from 267 to 400 cubic inches (including the popular SBC 305 and SBC 350 V8 blocks).
Q2: Does this SBC exhaust header clear power steering, power brakes, or air conditioning systems?
A2: No, please note the specific fitment restrictions for this model (Model: EH28166). It is designed for RWD applications with no power steering, no power brakes, and no air conditioning. If your classic Camaro features these factory options, modifications or alternative header styles will be necessary.
Q3: Can I install these FLASHARK headers on a manual transmission Camaro?
A3: This specific header model is verified to fit automatic transmission setups (both column shift and floor shift). It is not compatible with standard (manual) transmission column shift or floor shift configurations out of the box.
Q4: What are the exact pipe dimensions and specifications of this 2nd Gen Camaro header?
A4: The FLASHARK EH28166 header features a high-flow layout with a 1.65-inch inlet diameter and a 3-inch outlet collector diameter. The primary construction features 4 x 1.75" manifold piping collecting into a 1 x 3.5" major pipe, optimized to smoothly scavenge exhaust gases from your Small Block Chevy engine.
Q5: What material is used to construct this Camaro SBC V8 exhaust header?
A5: These high-performance headers are manufactured from premium-grade Stainless Steel and finished with a striking mirror polish. The stainless steel construction ensures superior durability, rust resistance, and high-temperature tolerance compared to stock iron manifolds.
Q6: What performance and sound gains can I expect from upgrading to FLASHARK headers?
A6: Upgrading from stock cast-iron manifolds to FLASHARK stainless steel headers eliminates exhaust backpressure by giving each cylinder its own dedicated tube. This allows exhaust gases to exit faster, unlocking noticeable horsepower and torque gains while giving your 1970-1981 Camaro an aggressive, deep muscle car exhaust sound.
Q7: Is this Camaro SBC header a direct bolt-on installation, or is welding required?
A7: Yes, this product is designed as a direct bolt-on upgrade, meaning no internal modifications are required for mounting onto the engine block. However, adapting the 3-inch outlet collectors to your existing mid-pipes or cat-back exhaust system may require standard exhaust adapters or custom routing.
Q8: Do these headers fit standard or aftermarket cylinder heads like Vortec or D-port heads?
A8: These headers are tailored for standard Small Block Chevy (SBC) cylinder head configurations. If your 1970-1981 Camaro is upgraded with aftermarket heads (such as Vortec, ZZ4, or D-port heads), we recommend verifying exhaust port alignment before purchasing, as port spacing and shapes can vary.
Q9: What comes included in the package with the FLASHARK Camaro SBC Exhaust Header?
A9: The package (SKU: FLES08247) includes both the driver and passenger-side mirror-polished stainless steel exhaust headers, along with premium installation gaskets and essential mounting hardware required for a complete, leak-free bolt-on installation.
Q10: How does the FLASHARK header compare to thick cast-iron exhaust manifolds?
A10: Cast-iron manifolds are thick, heavy, and restrictive, causing severe backpressure that chokes engine performance. FLASHARK headers use lightweight, mandrel-bent stainless steel tubes that accelerate exhaust gas scavenging, making them the far better choice for any classic Camaro restoration or street machine build.
Q11: Will this header fit a Big Block Chevy (BBC) or LS-swapped 2nd Gen Camaro?
A11: No, this specific model is designed exclusively for traditional Small Block Chevy (SBC) V8 configurations (267-400 V8). If you are running a Big Block Chevy (396/427/454) or executing an LS swap, FLASHARK provides separate, dedicated headers optimized for those specific engine blocks.
Q12: How do I maintain the brilliant mirror-polished finish of my stainless steel headers?
A12: To preserve the mirror polish, thoroughly clean the headers with rubbing alcohol or a dedicated stainless steel cleaner prior to your first engine startup to remove skin oils and grease. Please note that high-performance stainless steel naturally develops a unique golden/amber patina under intense exhaust temperatures, which is a sign of high-quality material reacting to heat.
