طقم إدخال الصوت 94db كاتم RS-4، 1.250 بوصة (INS-13-K)

It fit perfectly onto my RS-4 muffler and noticeably softened the bark without totally killing the sound. The kit includes everything needed for the swap, which made the whole process straightforward.

Took about ten minutes to swap in, and the difference is noticeable right away — the tone is much tamer without killing all the bark. The 94db rating feels about right for my setup, and it’s nice having the option to go quiet for certain areas.

Slipped right into my RS-4 with no issues and cut the noise just enough for my neighborhood. The 94db rating is spot-on for what I needed.
