R-34 マフラー用 低音量インサートキット (INS-29-K)

Took the edge off the exhaust note just as promised—the dB drop is noticeable but the tone stays deep and clean. Fit into my R-34 without any wrestling, and the whole swap took under an hour. Exactly what I needed to quiet things down for the neighborhood.

Install took maybe fifteen minutes and the fit is spot-on, no rattling or gaps. It drops the bark to a manageable level while keeping that deep tone intact, which is exactly what I needed for daily driving.

Finally, the drone on the highway is gone. This insert dropped the exhaust note perfectly for my R-34—still sounds mean, but I can actually hold a conversation now. Fit was dead-on, no rattling at all.
