The A90 Toyota Supra has captured the hearts of car enthusiasts worldwide with its sleek design and powerful performance. One of the most popular modifications among owners is upgrading the downpipe, which significantly enhances the vehicle’s exhaust sound and overall performance. In this article, we will conduct a sound test comparing two renowned downpipe brands: Akrapovic and Invidia. Both brands promise a unique deep exhaust note, but how do they stack up against each other?
Understanding Downpipes
A downpipe is a crucial component of a vehicle’s exhaust system. It connects the turbocharger to the rest of the exhaust system, allowing exhaust gases to exit the engine more efficiently. Upgrading to a high-performance downpipe can lead to:
- Increased horsepower and torque
- A more aggressive exhaust note
- Improved turbo response
- Enhanced overall driving experience
