KHROME WERKS - HP-Plus® Kit (Manufacturer's Ref: 202399)

Designed for vintage/classic enthusiasts who want to master the tone of their silencers, this HP-Plus® Kit is a simple and effective insert solution. It reduces noise by approximately 4 dB at idle while improving low-end performance, with minimal power loss at high revs — without altering the external line of the silencer.

• Installation: bolts in place, requires removal of the silencers for installation.
