Pro Series Mufflers 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.

	PRO Series w/Turndown These are the same as the standard Pro series mufflers except with a "turn-down" outlet integrated into the muffler for additional sound suppression in racing applications.

	HP-2 Series "Shorty" - 409S Constructed with an 12" long, painted 409S outer shell, and 409 Internal components. Available in 2.00", 2.25", and 2.50" inlet/outlet sizes.

	HP-2 Series Mufflers - 409S Constructed with an 18" long, painted 409S outer shell, and 409 Internal components. Available in 2.00", 2.25", and 2.50" inlet/outlet sizes.
