Are Aftermarket Exhausts Worth It?
The automotive aftermarket is filled with various modifications that promise enhanced performance, and one of the most popular upgrades is the exhaust system. This article delves into the world of aftermarket exhausts, specifically testing the Borla and HKS systems on a 1G Eclipse, aiming for significant horsepower gains.
Understanding Exhaust Systems
The exhaust system of a vehicle plays a crucial role in its performance. It is responsible for directing harmful gases away from the engine, reducing noise, and improving overall efficiency. A well-designed exhaust system can lead to better airflow, which translates to increased horsepower and torque.
Components of an Exhaust System
- Exhaust manifold
- Catalytic converter
- Resonator
- Muffler
- Exhaust pipes
Why Upgrade to Aftermarket Exhausts?
Many car enthusiasts choose to upgrade their exhaust systems for several reasons, including:
- Improved performance
- Enhanced sound quality
- Weight reduction
- Customization options
Testing Methodology
To evaluate the effectiveness of the Borla and HKS exhaust systems, we conducted a series of tests on a 1G Eclipse. The testing involved:
- Baseline dyno runs with the stock exhaust
- Installation of the Borla exhaust system
- Dyno runs with the Borla system
- Installation of the HKS exhaust system
- Final dyno runs with the HKS system
Results of the Exhaust Tests
After completing the tests, we recorded the horsepower gains with both aftermarket exhaust systems compared to the stock setup. The results were as follows:
- Stock Exhaust: 130 HP
- Borla Exhaust: 145 HP (15 HP gain)
- HKS Exhaust: 140 HP (10 HP gain)
Analysis of the Results
The Borla exhaust system outperformed the HKS system in terms of horsepower gains. However, both aftermarket options provided a noticeable improvement over the stock exhaust. The decision on which exhaust to choose may depend on personal preferences regarding sound, aesthetics, and budget.
Sound Comparison
Sound is a critical factor for many enthusiasts. The Borla exhaust produced a deeper, more aggressive tone, while the HKS offered a slightly quieter experience with a smoother sound profile. This difference can influence a buyer’s choice depending on their desired auditory experience.
Build Quality and Design
Both the Borla and HKS exhaust systems exhibited high-quality construction. The Borla system featured a polished stainless steel finish, while the HKS system had a more subdued look with its matte finish. The choice between the two may come down to personal aesthetics.
Cost Considerations
Pricing is an essential factor when considering aftermarket exhausts. The Borla system is generally priced higher than the HKS system, reflecting its performance gains and build quality. However, the HKS exhaust still provides a good balance of performance and affordability.
Conclusion
Aftermarket exhausts can be a worthwhile investment for those looking to enhance their vehicle’s performance and sound. The tests conducted on the 1G Eclipse demonstrated that both the Borla and HKS exhaust systems provided significant gains over the stock setup, with the Borla leading in horsepower increase. Ultimately, the choice between the two will depend on individual preferences in sound, style, and budget.
Final Thoughts
When considering an aftermarket exhaust, it is essential to weigh the benefits against the costs and to choose a system that aligns with your performance goals and personal preferences. With proper research and testing, you can find an exhaust system that truly enhances your driving experience.
