The Honda S2000 AP2 is a beloved sports car known for its high-revving engine and excellent handling. One of the most popular modifications among enthusiasts is the installation of an aftermarket exhaust system. In this article, we will explore how a HKS exhaust system can improve both the sound and power of the S2000 AP2, potentially adding up to 15 horsepower.
Understanding the HKS Exhaust System
The HKS exhaust system is designed to enhance the performance of the S2000 AP2 by reducing back pressure and improving exhaust flow. This results in a more efficient engine operation, which can lead to increased horsepower and torque. Additionally, the HKS system is known for its distinctive sound that many enthusiasts find appealing.
Key Features of the HKS Exhaust System
- High-quality stainless steel construction for durability
- Mandrel-bent piping for smooth exhaust flow
- Lightweight design to reduce overall vehicle weight
- Optimized for performance gains without sacrificing daily drivability
Performance Testing Methodology
To evaluate the performance improvements provided by the HKS exhaust system, a series of tests were conducted. These tests included:
- Baseline dyno runs with the stock exhaust system
- Installation of the HKS exhaust system
- Follow-up dyno runs to measure power gains
- Sound level measurements to assess acoustic improvements
Baseline Performance Results
Before the installation of the HKS exhaust system, the S2000 AP2 produced a baseline power output of approximately 220 horsepower at the wheels. This figure is typical for a stock vehicle and serves as a reference point for measuring the impact of the exhaust upgrade.
Post-Installation Performance Results
After installing the HKS exhaust system, the S2000 AP2 was subjected to another round of dyno testing. The results were impressive:
- Power output increased to 235 horsepower at the wheels
- Torque improved by approximately 10 lb-ft
- Peak power achieved at a higher RPM, enhancing the driving experience
Sound Quality Improvement
In addition to the power gains, the sound produced by the HKS exhaust system is a significant upgrade over the stock setup. The HKS system offers a deeper, more aggressive tone that resonates well with performance enthusiasts. Sound level measurements indicated an increase in volume, particularly at higher RPMs, without being overly intrusive during everyday driving.
Conclusion
The HKS exhaust system proves to be a valuable modification for the Honda S2000 AP2, offering a combination of performance and sound enhancements. With an increase of up to 15 horsepower and a more engaging exhaust note, it is an excellent choice for those looking to elevate their driving experience. Whether on the track or the street, the HKS exhaust system delivers noticeable benefits that can enhance the overall enjoyment of the S2000 AP2.
