First Gen Nsx Mods: Comparing Aftermarket Headers and Catalytic Converters for Power and Cost

by

The first-generation Acura NSX is a beloved sports car known for its exceptional engineering and performance. As enthusiasts look to enhance their vehicles, aftermarket modifications play a crucial role in unlocking additional power and improving overall driving experience. This article focuses on two popular modifications: aftermarket headers and catalytic converters. We will compare their impact on power output and cost, helping you make an informed decision for your NSX.

Overview of Aftermarket Headers

Aftermarket headers are designed to replace the factory exhaust manifold, allowing for improved exhaust flow. This modification can lead to increased horsepower and torque, enhancing the overall performance of the NSX.

Benefits of Aftermarket Headers

Installing aftermarket headers offers several advantages:

  • Improved Exhaust Flow: Headers reduce back pressure, allowing exhaust gases to exit more efficiently.
  • Increased Power: Enhanced flow can lead to noticeable gains in horsepower and torque.
  • Weight Reduction: Many aftermarket headers are lighter than stock units, contributing to better performance.
  • Sound Enhancement: Headers can give your NSX a more aggressive exhaust note.

Some of the most popular aftermarket header brands for the first-gen NSX include:

  • Comptech: Known for their high-quality stainless steel headers that offer excellent performance gains.
  • DC Sports: Offers a balance of performance and affordability with their headers.
  • SMSP: Focuses on maximizing power with their tuned headers designed specifically for the NSX.

Overview of Aftermarket Catalytic Converters

Aftermarket catalytic converters serve to replace the factory unit, often with high-flow designs that allow for better exhaust flow while still meeting emissions standards. This modification can also contribute to increased power and improved throttle response.

Benefits of Aftermarket Catalytic Converters

Upgrading to a high-flow catalytic converter provides several benefits:

  • Enhanced Performance: High-flow designs reduce exhaust restrictions, improving performance.
  • Emissions Compliance: Many aftermarket options are designed to meet emissions standards, making them street legal.
  • Improved Throttle Response: Less exhaust back pressure can lead to quicker throttle response.
  • Durability: Aftermarket converters often use higher quality materials for increased longevity.

Some reputable brands for aftermarket catalytic converters include:

  • HKS: Offers high-performance catalytic converters that are known for their durability and efficiency.
  • MagnaFlow: Provides a wide range of high-flow converters that balance performance and emissions compliance.
  • DC Sports: Known for their performance-oriented catalytic converters that enhance exhaust flow.

Comparing Power Gains

When considering modifications, understanding the power gains associated with each option is essential. Both aftermarket headers and catalytic converters can contribute to increased performance, but their effects can vary.

Power Gains from Headers

Aftermarket headers can yield significant horsepower increases, often ranging from 10 to 25 horsepower depending on the design and accompanying modifications. This increase is primarily due to improved exhaust flow and reduced back pressure.

Power Gains from Catalytic Converters

High-flow catalytic converters typically provide smaller power gains compared to headers, usually in the range of 5 to 15 horsepower. However, they can still enhance overall engine efficiency and throttle response.

Cost Comparison

Cost is a critical factor when considering modifications. Understanding the price range for aftermarket headers and catalytic converters can help you budget effectively.

Cost of Aftermarket Headers

Aftermarket headers typically range from $500 to $1,500, depending on the brand and materials used. Premium options may offer better performance but come at a higher price point.

Cost of Aftermarket Catalytic Converters

High-flow catalytic converters usually cost between $200 and $800. The price varies based on the manufacturer and whether the converter is designed for street use or racing.

Conclusion

Both aftermarket headers and catalytic converters offer unique benefits for enhancing the performance of the first-generation NSX. Headers provide significant power gains and improved exhaust flow, while catalytic converters offer a balance of performance and emissions compliance. When deciding between the two, consider your performance goals, budget, and whether you want to prioritize power or emissions standards. Ultimately, the right modification will depend on your personal preferences and driving style.
