KHROME WERKS Sound Reduction Kit — Quiet Insert Kit, for 3" HP-Plus® mufflers, 6-1/2" resonator

The Sound Reduction Kit provides easy, bolt-in sound reduction for 3" HP-Plus® mufflers. 🔇

It takes off about 4 dB at idle and improves low-end torque with 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. Installation requires removal of the mufflers.

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

Kit includes machined discs and two 7-1/2" 1/4"-20 bolts and two prevailing-torque nuts. Made in the U.S.A.
