The A90 Supra has quickly become a favorite among car enthusiasts, thanks to its impressive performance and tuning potential. One of the most effective ways to enhance its power output is by upgrading the downpipe. This article will explore the dyno results from various brands, helping you make an informed decision on which downpipe to choose for maximizing your A90 Supra’s power.
Understanding the Importance of a Downpipe
A downpipe is a critical component of the exhaust system, connecting the turbocharger to the rest of the exhaust. Upgrading the downpipe can significantly reduce back pressure, allowing the turbo to spool faster and improving overall engine efficiency. This leads to better throttle response and increased horsepower and torque.
