Honda S2000: Best Headers - The Top Performance Upgrades For Serious Speed
The Honda S2000. A name whispered with reverence amongst driving enthusiasts. This iconic roadster, born from Honda’s motorsport legacy, boasts exhilarating handling, a high-revving engine, and a timeless design. But even perfection can be improved. For those seeking to unlock the full potential of their AP1 or AP2 S2000, upgrading the exhaust system, particularly the headers, is a crucial step. This article dives deep into the world of Honda S2000 headers, exploring the best options and their impact on performance.
Understanding the Role of Headers
Headers, also known as exhaust manifolds, are the first component of the exhaust system, directly bolted to the engine’s cylinder head. They collect exhaust gases from each cylinder and merge them into a single pipe, directing them towards the catalytic converter and further down the exhaust. The design of the headers significantly impacts engine performance, specifically:
- Exhaust Gas Scavenging: Headers are designed to use the pressure waves created by exhaust pulses to help “suck” the exhaust gases out of the cylinders. This process, called scavenging, improves engine breathing.
- Power and Torque Gains: Properly designed headers can optimize exhaust flow, leading to improvements in both horsepower and torque, particularly in the mid-to-high RPM range where the S2000 thrives.
- Engine Response: Enhanced exhaust flow often results in a more responsive throttle and a quicker acceleration feel.
Key Factors to Consider When Choosing Headers
Selecting the right headers for your S2000 involves considering several factors:
- Material:
- Stainless Steel: The most common choice, offering excellent durability, corrosion resistance, and a good balance of performance and cost.
- Titanium: The premium option, known for its incredible strength-to-weight ratio and superior heat resistance, resulting in potentially the greatest performance gains. However, titanium headers are significantly more expensive.
- Design:
- 4-2-1 Headers: These headers feature a longer primary tube design that merges the exhaust gases from four cylinders into two, and then into one. They typically offer better low-end and mid-range torque.
- 4-1 Headers: These headers have shorter primary tubes that merge the exhaust gases from four cylinders directly into one. They are generally optimized for high-RPM power gains.
- Tube Diameter: The diameter of the header tubes influences exhaust flow. Generally, larger tube diameters are better for high-RPM power, while smaller diameters can improve low-end torque. Matching the tube diameter to your engine’s modifications is crucial.
- Fitment: Ensure the headers are specifically designed for the AP1 (2000-2003) or AP2 (2004-2009) S2000, as there are subtle differences.
- Budget: Headers vary significantly in price. Set a realistic budget and prioritize features that align with your performance goals.
Top Header Options for the Honda S2000
While the “best” header depends on your specific needs and goals, here are some of the top-rated and most popular options:
- J’s Racing Headers: Known for their high-quality construction and proven performance gains. J’s Racing headers often provide excellent mid-range and top-end power.
- Toda Racing Headers: Renowned for their meticulous design and manufacturing. Toda headers are often favored for their responsiveness and power delivery.
- GruppeM Headers: Crafted from high-quality stainless steel and designed for optimal exhaust flow, offering significant performance improvements.
- Berk Technology Headers: A popular choice offering a balance of performance and value. Berk headers are often praised for their ease of installation and noticeable power gains.
- PLM (Performance L.L.C.) Headers: Offer great value for the price point. PLM headers provide performance gains and are a good option for those on a budget.
Installation and Considerations
Installing headers requires mechanical expertise. While some experienced individuals may attempt a DIY installation, it’s generally recommended to have a qualified mechanic perform the work.
- Professional Installation: Ensures proper fitment, prevents leaks, and optimizes performance.
- Catalytic Converter Compatibility: Check if the headers are compatible with your existing catalytic converter or if a new one is required.
- Tuning: After installing headers, it’s highly recommended to get your car professionally tuned to maximize the performance gains and ensure optimal engine operation.
Beyond Headers: Complementary Upgrades
To maximize the benefits of your new headers, consider these complementary upgrades:
- High-Flow Catalytic Converter: Reduces exhaust restriction further, improving flow and performance.
- Cat-Back Exhaust System: Optimizes the entire exhaust flow path, enhancing both performance and sound.
- Cold Air Intake: Improves airflow to the engine, complementing the exhaust upgrades.
- ECU Tuning: Fine-tunes the engine’s parameters to match the new exhaust system, further optimizing performance.
Conclusion: Unleash the Beast Within
Upgrading the headers on your Honda S2000 is a significant step toward unlocking its full performance potential. By choosing the right headers, considering other complementary upgrades, and ensuring professional installation and tuning, you can experience a noticeable increase in horsepower, torque, and overall driving enjoyment. Whether you’re a track enthusiast or a spirited street driver, investing in quality headers is a worthwhile endeavor that will transform your S2000 into an even more exhilarating machine.
FAQs
1. Will I need to retune my S2000 after installing headers?
Yes, it is highly recommended to retune your S2000’s ECU (Engine Control Unit) after installing headers. This ensures the engine’s parameters are optimized to take full advantage of the improved exhaust flow and prevent potential issues like lean conditions.
2. What are the potential downsides of aftermarket headers?
Potential downsides can include increased exhaust noise (depending on the design), the need for professional installation, and the possibility of failing emissions testing if the headers are not CARB-compliant (check your local regulations).
3. Is it worth upgrading headers on a stock Honda S2000?
Even on a stock S2000, upgrading headers can provide performance benefits, particularly in terms of throttle response and mid-range power. However, the gains may be more significant when combined with other performance upgrades like a cold air intake and ECU tuning.
4. How much power can I expect to gain from a header upgrade?
Power gains vary depending on the header design, the engine’s modifications, and the quality of the tuning. Generally, you can expect to see gains of 10-20 horsepower, sometimes more, particularly in the mid-to-high RPM range.
5. Can I install headers myself?
While it’s possible to install headers yourself if you have the necessary mechanical skills, tools, and experience, professional installation is generally recommended. This ensures proper fitment, prevents leaks, and often includes the necessary tuning for optimal performance.
