طقم إدخال الصوت لكاتم RS-12، 1.500 بوصة (INS-39-K)

Installed this RS-12 insert kit and the sound difference is noticeable, especially at low rpm where it was previously loud. The non-spark arrested design wasn't an issue for my application. Very pleased with how easy the swap-out was.

The low-volume insert kit made a real difference on my RS-12 setup, and the fit was precise right out of the box. Installation took about ten minutes, and the muffler now handles the sound restrictions exactly as needed.

Swapped this in to meet a local sound ordinance and the kit was a perfect fit for the RS-12's existing housing. The decibel drop is noticeable, though the exact reduction will vary with your setup—still, it took the edge off without killing the flow.
