Sound Reduction Kit

Sound Reduction Kit

Easy, bolt-in sound reduction for 3" HP-Plus® mufflers

Takes off 4dB at idle and improves low-end torque - minimal loss of top-end horsepower

The machined discs with tapered bosses fit into each end of the patented resonator near the exit end of the mufflers and are retained by the supplied bolts and nuts

This kit is designed to use with three-ball style resonators that are 6-1/2" long

Will also fit most other mufflers (four-ball style resonators) if 1/4"-20 x 11.00" threaded rods are substituted for the supplied bolts

Installation requires removal of the mufflers

Kit includes machined discs and (2) 7-1/2" 1/4"-20 bolts and two prevailing torque nuts

Made in the U.S.A.
