When it comes to enhancing the performance of your vehicle, aftermarket modifications can make a significant difference. Among these modifications, headers are often a popular choice for car enthusiasts. This article explores whether aftermarket headers are worth the investment by testing the Invidia N1 headers against the OEM (Original Equipment Manufacturer) headers on the first generation NSX.
Understanding Headers
Headers are an essential part of your vehicle’s exhaust system. They are designed to improve the flow of exhaust gases from the engine, which can lead to better performance. The primary purpose of aftermarket headers is to reduce back pressure and enhance horsepower and torque.
Aftermarket vs. OEM Headers
OEM headers are designed to meet the manufacturer’s specifications, providing reliability and adequate performance for everyday driving. In contrast, aftermarket headers, like the Invidia N1, are engineered for higher performance, often utilizing materials and designs that can enhance exhaust flow.
Benefits of Aftermarket Headers
- Increased Performance: Aftermarket headers can significantly boost horsepower and torque.
- Improved Sound: Many aftermarket headers provide a more aggressive exhaust note.
- Weight Reduction: Aftermarket options may be lighter than OEM headers, improving overall vehicle dynamics.
Potential Drawbacks
- Cost: Aftermarket headers can be expensive, and installation may require professional help.
- Legal Issues: Some aftermarket headers may not meet emissions regulations.
- Installation Complexity: Installation can be more challenging than simply replacing OEM parts.
Testing Methodology
To determine the effectiveness of the Invidia N1 headers compared to OEM headers, we conducted a series of tests on a first generation NSX. The tests included a dyno run for power measurements and a subjective evaluation of sound and driving experience.
Dyno Testing
We began with a baseline run using the OEM headers to establish a performance benchmark. The NSX was tested under controlled conditions to ensure accurate results. After replacing the OEM headers with the Invidia N1 headers, we conducted additional dyno runs to measure any changes in horsepower and torque.
Sound Evaluation
In addition to power testing, we evaluated the sound produced by both header setups. The subjective experience of sound can greatly influence a driver’s enjoyment of their vehicle. We compared the exhaust note at various RPMs to assess the tonal differences between the two headers.
Results
The results of our testing provided valuable insights into the performance of the Invidia N1 headers compared to the OEM headers.
Power Gains
The dyno results showed a noticeable increase in horsepower and torque with the Invidia N1 headers. Specifically, we recorded a gain of approximately 15-20 horsepower and a similar increase in torque across the RPM range. This improvement demonstrates the effectiveness of aftermarket headers in enhancing engine performance.
Sound Comparison
In terms of sound, the Invidia N1 headers produced a deeper and more aggressive exhaust note compared to the OEM headers. Drivers reported a more engaging driving experience, especially during acceleration. The sound was not overly loud, making it suitable for daily driving while still providing a sportier feel.
Cost Considerations
When considering aftermarket headers, cost is an important factor. The Invidia N1 headers typically retail for around $1,200 to $1,500, depending on the retailer. Installation costs can vary, with professional installation ranging from $300 to $600, depending on labor rates in your area.
Cost vs. Performance
While the initial investment for aftermarket headers may seem high, the performance gains can justify the cost for many enthusiasts. The increased horsepower and torque, combined with the enhanced sound, can significantly improve the driving experience. However, it’s essential to weigh these benefits against your budget and driving needs.
Conclusion
In summary, aftermarket headers, such as the Invidia N1, can provide substantial performance improvements over OEM headers on the first generation NSX. With increased horsepower, torque, and a more aggressive exhaust note, they offer an appealing upgrade for car enthusiasts. However, potential buyers should carefully consider the costs and whether the benefits align with their driving goals and budget.
Final Thoughts
Ultimately, the decision to invest in aftermarket headers should be based on individual preferences and driving habits. For those seeking enhanced performance and a more thrilling driving experience, aftermarket headers like the Invidia N1 are worth considering. However, for daily drivers who prioritize reliability and cost-effectiveness, sticking with OEM headers may be the better choice.
