The A90 Supra has garnered significant attention in the automotive community, particularly for its performance and tuning potential. One of the most impactful modifications for improving sound and performance is the downpipe. In this article, we will conduct a sound test comparing three popular downpipe options: Borla, Remus, and HKS.
Understanding Downpipes
Downpipes are integral components of a vehicle’s exhaust system. They connect the turbocharger to the rest of the exhaust system and play a crucial role in reducing back pressure, improving turbo spool, and enhancing exhaust sound. Choosing the right downpipe can dramatically affect your vehicle’s performance and auditory experience.
Overview of Downpipe Options
- Borla: Known for its aggressive sound and high-quality materials.
- Remus: Offers a refined tone with a focus on performance and durability.
- HKS: Renowned for its racing heritage and distinctive sound profile.
Sound Test Methodology
To accurately compare the sound output of each downpipe, we conducted a series of tests under controlled conditions. Each downpipe was installed on the same A90 Supra, and sound measurements were taken at various RPMs. The following conditions were maintained:
- Same vehicle setup and tuning.
- Consistent ambient temperature and weather conditions.
- Sound measurements taken using a calibrated decibel meter.
Sound Test Results
Below are the results from our sound tests, detailing the audio characteristics of each downpipe option:
Borla Downpipe Sound
The Borla downpipe produced a loud and aggressive sound, particularly at higher RPMs. The tone was deep and resonant, making it a favorite among enthusiasts looking for a sporty experience.
Remus Downpipe Sound
The Remus downpipe offered a more refined sound, with a smooth and consistent tone throughout the RPM range. It was less aggressive than the Borla but provided a satisfying auditory experience for those who prefer a more subtle enhancement.
HKS Downpipe Sound
The HKS downpipe showcased a unique sound profile, characterized by a raspy tone that many found appealing. It had a distinct presence, especially during acceleration, making it a strong contender for those seeking a race-inspired sound.
Comparative Analysis
When comparing the three downpipes, several factors came into play:
- Sound Aggressiveness: Borla > HKS > Remus
- Sound Quality: Remus > HKS > Borla
- Overall Preference: Subjective, based on individual taste
Conclusion
Choosing the right downpipe for your A90 Supra depends on your personal preferences regarding sound and performance. The Borla downpipe is perfect for those who want an aggressive tone, while the Remus offers a more refined experience. The HKS downpipe stands out with its unique sound profile, appealing to racing enthusiasts. Ultimately, each option has its merits, and the best choice will vary from driver to driver.
Final Thoughts
Before making a decision, it is advisable to listen to sound clips and consider your driving style. Each downpipe will influence not only the sound but also the overall driving experience of the A90 Supra. Happy tuning!
