Aftermarket headers are a popular modification for car enthusiasts looking to improve performance and sound. In this article, we will explore the effectiveness of aftermarket headers, specifically comparing Borla and Toda headers on the first-generation Acura NSX.
Understanding Aftermarket Headers
Aftermarket headers replace the factory exhaust manifold to enhance exhaust flow, resulting in improved engine performance and sound. They are designed to reduce back pressure and optimize the engine’s efficiency.
Benefits of Aftermarket Headers
- Improved horsepower and torque
- Enhanced exhaust sound
- Better throttle response
- Potential weight savings
Testing Methodology
To evaluate the performance of Borla and Toda headers, we conducted a series of tests on a first-generation NSX. The tests included dyno runs and sound measurements to quantify power gains and evaluate sound characteristics.
Dyno Testing
We performed controlled dyno runs with both headers installed. The baseline was established with the factory exhaust system, followed by individual tests for each aftermarket header.
Sound Testing
Sound tests were conducted in a quiet environment to capture the unique exhaust notes of each header. This included idle, acceleration, and full throttle sound clips.
Results of the Testing
The results from our testing provided valuable insights into the performance and sound characteristics of both Borla and Toda headers.
Power Gains
The dyno results showed a clear difference in power gains between the two headers:
- Borla Headers: Increased power by 15 whp
- Toda Headers: Increased power by 12 whp
Sound Characteristics
In terms of sound, both headers offered distinct characteristics:
- Borla: Deep and aggressive tone with a noticeable growl at high RPMs
- Toda: Smooth and refined sound, maintaining a more subtle profile
Cost vs. Performance
When considering aftermarket headers, it’s essential to weigh the cost against the performance benefits. Both Borla and Toda headers come at a premium price, but the performance improvements may justify the investment for some enthusiasts.
Installation Considerations
Installing aftermarket headers can be a complex process. Here are some considerations:
- Professional installation is recommended for optimal fitment
- Potential need for additional modifications (e.g., new gaskets, heat shielding)
- Check local emissions regulations before installation
Conclusion
Aftermarket headers can provide significant performance and sound improvements for the first-generation NSX. Our testing showed that both Borla and Toda headers offer unique benefits, and the choice ultimately depends on individual preferences for sound and power.
For enthusiasts looking to enhance their NSX experience, investing in aftermarket headers is certainly worth considering.
