The A90 Toyota Supra has become a benchmark in the automotive world, especially among car enthusiasts looking to enhance performance. One of the most popular modifications is the exhaust system, with Greddy and Invidia being two of the leading brands in this market. This article will delve into a dyno comparison of Greddy vs Invidia exhaust systems for the A90 Supra, highlighting their power gains and overall performance.
Understanding Exhaust Systems
An exhaust system is crucial for a vehicle’s performance as it affects how efficiently the engine expels exhaust gases. Upgrading to a high-performance exhaust can lead to improved horsepower, torque, and overall engine efficiency. For the A90 Supra, choosing the right exhaust system can significantly impact its performance on the track and the street.

Dyno Comparison: Greddy vs Invidia
To determine which exhaust system provides better performance for the A90 Supra, a series of dyno tests were conducted. Both systems were tested under identical conditions to ensure accurate results.
Testing Methodology
The dyno tests involved measuring horsepower and torque at the wheels. Each exhaust system was installed on the same A90 Supra, which was then run on a dynamometer to gather data. The following metrics were recorded:
- Baseline performance with stock exhaust.
- Performance with Greddy exhaust.
- Performance with Invidia exhaust.
Results of the Dyno Tests
The results of the dyno tests revealed interesting insights into the performance gains provided by each exhaust system:
- Greddy Exhaust: Increased horsepower by 15 whp and torque by 12 lb-ft.
- Invidia Exhaust: Increased horsepower by 18 whp and torque by 15 lb-ft.
Power Gains Analysis
Both exhaust systems demonstrated significant power gains over the stock exhaust. However, the Invidia system outperformed the Greddy system in both horsepower and torque increases. This suggests that Invidia may provide a more efficient exhaust flow, contributing to better overall performance.
Sound Comparison
While performance is crucial, the sound of an exhaust system is equally important for many enthusiasts. Both Greddy and Invidia offer distinct sound profiles:
- Greddy: Produces a deep, throaty growl that resonates well at higher RPMs.
- Invidia: Offers a more aggressive tone with a higher pitch, providing a sporty feel.
Conclusion
In conclusion, both Greddy and Invidia exhaust systems offer substantial performance enhancements for the A90 Supra. While Greddy excels in build quality and sound, Invidia edges out in terms of horsepower and torque gains. Ultimately, the choice between these two systems will depend on individual preferences regarding sound and performance priorities.
For A90 Supra owners looking to upgrade their exhaust, considering these factors will help in making an informed decision that aligns with their driving style and performance goals.
