طقم إدخال الصوت 2M-MAX RS-4 كاتم صوت، 1.375 بوصة (INS-2M26-K)

Finally got the RS-4 back on the buggy with this insert kit, and it’s just the right reduction for our track. The non-spark arrested design is exactly what I needed for closed-course use.

Installing this 1.375" insert dropped the bark of my RS-4 to a much more pleasant tone without killing all the flow. The non-spark-arrested design was exactly what I needed for my track setup.

I was worried the sound would still be too loud, but this insert dropped the decibels just enough for my neighborhood runs. The 1.375" size fit perfectly into my existing RS-4 setup without any modifications.
