When John Schultz of HPI decided to drop a small block motor in his 1/8 scale Savage X and run against the smaller and lighter 1/10 scale trucks in the No Limit R/C World Finals at Digger’s Dungeon in NC, the largest R/C Monster Truck event in history, he knew he would need all the power he could get...

That’s why he chose the Buku Power Exhaust designed to maximize power throughout the entire RPM range. "The Buku pipe gave me an unbelievable increase in power." John was not only competitive, he defeated all challengers in head to head racing and brought home the 2008 Small Block World Title.

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.
