High-performance headers are a popular modification among automotive enthusiasts, especially for those looking to enhance the performance of their vehicles. In this article, we will explore whether high-performance headers are worth the investment by testing two popular options: Invidia and Grimmspeed on the FA20 engine.
Understanding High-Performance Headers
High-performance headers are designed to improve the flow of exhaust gases from the engine. This enhanced flow can lead to increased horsepower and torque, as well as improved throttle response. But what exactly makes these headers different from stock options?
- Material: Most high-performance headers are made from stainless steel or other lightweight materials.
- Design: They feature a tuned design that optimizes exhaust flow.
- Weight: High-performance headers are often lighter than stock headers, contributing to overall vehicle weight reduction.
Testing Methodology
To determine the effectiveness of the Invidia and Grimmspeed headers, we conducted a series of tests on a stock FA20 engine. The tests included:
- Baseline dyno runs with stock headers.
- Installation of Invidia headers followed by dyno testing.
- Installation of Grimmspeed headers followed by dyno testing.
Baseline Performance
Before installing the high-performance headers, we recorded the baseline performance of the FA20 engine. The stock headers provided a certain level of efficiency, but there was room for improvement.
- Peak horsepower: 200 hp
- Peak torque: 151 lb-ft
Invidia Headers Performance
After installing the Invidia headers, we conducted another round of dyno tests. The results showed a noticeable improvement in performance.
- Peak horsepower: 215 hp
- Peak torque: 158 lb-ft
The increase in horsepower and torque from the Invidia headers was impressive, showcasing their effectiveness in improving exhaust flow.
Grimmspeed Headers Performance
Next, we installed the Grimmspeed headers and repeated the dyno tests. The results were equally compelling.
- Peak horsepower: 210 hp
- Peak torque: 156 lb-ft
While the Grimmspeed headers did not outperform the Invidia headers, they still provided a significant boost over the stock setup.
Comparative Analysis
When comparing the two high-performance headers, both options demonstrated clear advantages over the stock headers. However, there are some distinctions worth noting.
- Invidia: Best overall performance gains with a more aggressive sound.
- Grimmspeed: Slightly less power but praised for build quality and fitment.
Cost Considerations
Cost is always a factor when considering modifications. The price of high-performance headers can vary significantly between brands and models.
- Invidia headers: Approximately $800
- Grimmspeed headers: Approximately $750
While both options require a significant investment, the performance gains may justify the expense for many enthusiasts.
Installation and Fitment
Installation of high-performance headers can be a complex task, requiring mechanical skill and the right tools. Both the Invidia and Grimmspeed headers were designed for a direct fit, but some users reported challenges during installation.
- Invidia: Slightly more challenging due to tighter bends.
- Grimmspeed: Generally easier to install with clear instructions.
Sound Comparison
Another important aspect of high-performance headers is the sound they produce. Both Invidia and Grimmspeed headers alter the exhaust note, but in different ways.
- Invidia: Aggressive and loud, appealing to those who want a sporty sound.
- Grimmspeed: Deeper and more refined, suitable for a more subtle approach.
Final Thoughts
So, are high-performance headers worth it? Based on our testing of the Invidia and Grimmspeed options, the answer is a resounding yes for those looking to enhance their FA20 engine’s performance.
- Invidia offers the best performance gains and an aggressive sound.
- Grimmspeed provides excellent build quality and a refined sound.
Ultimately, the choice between the two will depend on your personal preferences and performance goals. Both headers deliver significant improvements over stock headers, making them worthwhile investments for enthusiasts.
