While traditional tuned pipes must focus on only one RPM range for maximum effect, the Buku Power Exhaust System can boost performance throughout the entire RPM range. It’s the world’s only tuned pipe that dynamically adjusts its tuned length during use. The unique patent pending design of the Buku Power Exhaust System is the result of several years of development and thousands of dynamometer tests. This research has resulted in a truly revolutionary design that can produce more power than any other tuned pipe available today.
