聲音插入套件 99db RS-2 消音器，1.625 英吋 (INS-07-K)

This insert kit made a noticeable difference in the RS-2's bark without killing the flow completely. The 1.625" size slid right into place, and the non-spark arrested design is exactly what I needed for my range setup.

I needed a quieter option for my setup, and this 99db insert kit dropped the noise perfectly without killing performance. It was a straightforward swap onto the existing muffler, taking just a couple minutes.

It’s exactly what I needed to tone down the RS-2 on my setup, and the 99db rating matches what I’m getting at idle. Install was straightforward, though you’ll want to check your local rules since it’s not spark arrested.
