How loud are Yoshimura exhausts?
A. Since sound files are hard to hear online, it is best to compare them to other brands. The Yoshimura RS-3 Zyclone systems are one of the quietest systems on the market today that still offer good performance gains with minimal restriction. RS-3 Zyclone systems are 90-92dB while RS-3 Race systems are 95dB. All measurements are taken at the industry standard of 20″ away from the turndown tip at a 45-degree angle out from the tip. The motor is revved and held at 4,000 rpm in neutral. A reading is then taken and recorded. Round Zyclone systems are 95dB while round race systems are 101-105db depending on model.
