Gain up to 8–20 horsepower and improve fuel efficiency with FLASHARK's Honda Accord headers, specially designed for the 1998–2002 Honda Accord. Upgrading your exhaust headers not only increases power and torque but also enhances throttle response and delivers a deep, sporty exhaust tone. With these high-performance headers, your Accord can sound and feel like a true performance machine.
Additionally, installing these performance Honda Accord headers can improve your gas mileage by approximately 0.5 mpg. That might seem minor, but it adds up over time. If you drive 15,000 miles per year at $3 per gallon, you could save around $85 annually—nearly enough to pay for a full cat-back system over five years.
Best of all, FLASHARK headers feature a bolt-on design with no modifications required, making installation fast and hassle-free.
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.

Q1: What vehicles is the Flashark 3TC exhaust header compatible with?
A1: This performance exhaust header is precisely engineered for the 1974-1982 Toyota Corolla (E70/TE72 chassis) equipped with the 1.8L 3T-C SOHC Inline-4 engine. It is a perfect fit for all major trim levels, including the popular DLX and SR5.
Q2: What performance gains can I expect from this Toyota Corolla 1.8L header?
A2: By replacing the restrictive factory cast-iron manifold with our free-flowing 3TC header, you can expect an impressive gain of 8 to 20 horsepower. It significantly improves exhaust scavenging, resulting in better low-end torque and immediate throttle response.
Q3: Does this 1974-1982 Toyota Corolla exhaust header require any modifications to install?
A3: No, it does not. This Flashark header features a convenient, direct bolt-on design. It is engineered to seamlessly replace your OEM exhaust manifold without the need for custom welding or heavy modifications, making it perfect for DIY tuners.
Q4: What material is this 3TC header made from?
A4: To ensure long-lasting durability, corrosion resistance, and maximum heat management, this header is constructed from premium-grade stainless steel. It also features a sleek 3-stage mirror polish finish that will dramatically upgrade the aesthetics of your classic Corolla's engine bay.
Q5: Will this exhaust header fit my TE72 Corolla Wagon or Coupe?
A5: Yes! This 1.8L 3TC exhaust header is fully compatible with all body styles of the 1974-1982 Toyota Corolla E70/TE72 chassis. This includes the Sedan, Coupe, Hardtop, and Wagon variants.
Q6: What are the inlet and outlet dimensions of this Toyota 3TC performance header?
A6: This header is designed for optimal exhaust flow, featuring 1.5-inch primary tubes at the cylinder head flange that smoothly merge into a high-flowing 2.5-inch outlet collector.
Q7: How does this header improve upon the factory 3T-C exhaust manifold?
A7: Factory exhaust manifolds are made of thick, heavy iron and create severe back pressure, which chokes your engine's true potential. Our tubular stainless steel header gives each cylinder its own smooth-flowing tube, completely eliminating back pressure, reducing engine heat, and allowing your 1.8L engine to breathe properly.
Q8: Will upgrading to this 3TC header change the exhaust sound of my Corolla?
A8: Absolutely. Swapping out the stock manifold for our performance header will give your 1974-1982 Toyota Corolla a much deeper, more aggressive, and sportier exhaust tone that perfectly complements its classic retro heritage.
Q9: Can installing this Corolla 1.8L exhaust header improve fuel economy?
A9: Yes. Because the header relieves exhaust back pressure, your engine doesn't have to work as hard to expel spent exhaust gases. Many drivers experience a fuel efficiency improvement of approximately 0.5 mpg under normal daily driving conditions.
Q10: Is this header a good replacement for an old Pacesetter header on my SR5?
A10: Yes! If you are looking to upgrade an older, rusted mild-steel aftermarket header (like a Pacesetter) or replace a cracked OEM manifold on your DLX or SR5, this thick-flanged, stainless steel Flashark header is a massive upgrade in both longevity and performance.
Q11: Will this header fit other Toyota engines from that era?
A11: This specific exhaust header is strictly designed for the 1.8L 3T-C SOHC Inline-4 engine. It is not recommended for the smaller 2T-C or other Toyota engines unless they share the exact same exhaust port layout and engine bay clearance as the 74-82 Corolla.
Q12: Will this header fix the check engine light or exhaust leak issues?
A12: If your classic Corolla is suffering from poor performance or loud ticking noises due to a cracked factory cast-iron manifold, upgrading to this solid stainless steel header will permanently resolve the exhaust leak and restore your engine's smooth operation.
