طقم إدخال الصوت TRS 4.5 بوصة لكاتم الصوت، الشارع (TRS-INS-BK)

Installed this insert kit on my TRS muffler over the weekend, and the difference in sound pressure is exactly what I needed for neighborhood riding without being a nuisance. The low-volume insert slid right in without any modification to the existing hardware.

Took my bike from obnoxiously loud to a daily-drivable rumble — the low-volume insert fits right into the existing TRS muffler and the decibel drop was immediately noticeable on my first ride. Installation took under half an hour with basic tools.

Installed this in my TRS muffler and the difference is immediate—way more manageable without sounding like a restriction. The kit came with everything needed and bolted right up in under 20 minutes.
