The GR86 is a sports car that has captured the hearts of enthusiasts since its release. One of the most popular modifications among GR86 owners is the upgrade of the exhaust headers. Two leading brands in this space are Borla and Invidia. Both offer high-quality headers that promise to enhance performance and sound. In this article, we will delve into the details of these two brands to determine which headers boost power and tone better for the GR86.
Understanding Exhaust Headers
Exhaust headers are crucial components of a vehicle’s exhaust system. They are designed to improve the flow of exhaust gases from the engine, thereby enhancing performance. Upgrading to high-performance headers can lead to better throttle response, increased horsepower, and a more aggressive exhaust note.

- Material: Made from stainless steel for durability and corrosion resistance.
- Design: Features a tuned design for optimal exhaust flow.
- Sound: Known for producing a deep, aggressive exhaust note.
- Performance: Claims to increase horsepower and torque significantly.
Performance Metrics
When it comes to performance, Borla headers have been tested by many users. Reports indicate:
- Average horsepower gains of 10-15 HP.
- Torque increases in the low to mid-range RPMs.
Overview of Invidia Headers
Invidia is another prominent brand in the aftermarket exhaust industry. Their headers are designed with performance in mind and are popular among GR86 enthusiasts. Here are some notable features of Invidia headers:
- Material: Constructed from high-grade stainless steel for longevity.
- Design: Features a 4-2-1 design for improved exhaust scavenging.

Performance Metrics
Invidia headers have also shown promising results in performance tests. Users have reported:
- Average horsepower gains of 8-12 HP.
- Improved torque across a wider RPM range.
Comparing Power Gains
When comparing the power gains from Borla and Invidia headers, both brands offer noticeable improvements. However, Borla tends to provide slightly higher horsepower gains, particularly at higher RPMs. Invidia, on the other hand, offers a broader torque curve, which can be beneficial for daily driving.
Comparing Sound Profiles
Sound is a critical factor for many car enthusiasts. Borla headers produce a loud, aggressive tone that many find appealing for spirited driving. In contrast, Invidia headers provide a more refined sound, which may be preferable for those looking for a sporty yet subtle exhaust note.
Installation Considerations
Both Borla and Invidia headers are designed for a direct fit on the GR86, making installation relatively straightforward. However, some users have reported that:
- Borla headers may require slight modifications for optimal fit.
- Invidia headers typically fit without issues and come with all necessary hardware.
Price Comparison
Pricing can be a determining factor when choosing between Borla and Invidia headers. Generally, Borla headers are priced higher due to their premium materials and brand reputation. Invidia headers are more budget-friendly while still offering solid performance gains.
Final Thoughts
Ultimately, the choice between Borla and Invidia headers comes down to personal preference and priorities. If you prioritize maximum horsepower gains and an aggressive sound, Borla may be the better option. However, if you prefer a broader torque curve and a refined exhaust note at a more accessible price, Invidia could be the way to go.
Conclusion
Both Borla and Invidia headers provide excellent options for GR86 owners looking to enhance their vehicle’s performance and sound. By considering the factors outlined in this article, you can make an informed decision that best suits your driving style and preferences.
