Pro Series Performance Mufflers
Hushpower Pro Series Mufflers
In Huspowers continuing endeavor to bring the latest in performance and sound control technology to the street and race track, Hushpower is proud to introduce its newest line of performance Pro Series mufflers. These round-cased mufflers deliver ground breaking sound control while delivering maximum power and exhaust system efficiency. The Pro Series mufflers work on all applications ranging from street trucks, diesel "pullers" and RV “pushers” to every class of racing on dirt or asphalt.

During development, at the dyno and track, the new Hushpower Pro Series mufflers consistently delivered performance that is equal to or surpasses open pipe systems, while dramatically reducing sound levels across the RPM range. On a modified GMC diesel truck, racing on the DHRA circuit, one engine builder found 33 lbs/ft of torque and 13 horsepower at 2,850 RPM. Only a simple change out to the Hushpower from a competing performance muffler was made.

In the racing world, the Hushpower Pro Series Racing Mufflers (Parts 13016101 & 13516101) have been tested and mandated by the United States Auto Club (USAC) for the 2007 USAC Western States Divisions of sprint cars and midget sprints, as well as the C.R.A. sprint car series.

The internal construction of the Pro Series is T409 stainless steel and the outer case is fabricated from rugged 18-gauge aluminized steel. With part numbers available in 3.00, 3.50, 4.00, and 5.00 inch pipe diameters, we have the solution for your needs. Additionally the 3.00 and 3.50 inch models are also available with an integrated turn-down outlet for many racing applications.

The bottom line is that if you want to make more power, quietly, Hushpower Pro Series is the answer.
