طقم مانع الشرر RS-4S كاتم الصوت، 1.500" (SA-13-K-1)

Installed this on my RS-4 muffler and the weldnut on the insert was a nice upgrade—made screwing it in much less fiddly than I expected. Fits perfectly with the turn-out end cap, and it’s good to know it’s USFS approved for riding areas that require it.

I was dreading removing the old spark arrester, but this updated version with the weld nut inside the insert made installation a breeze on my muffler. It fits the 1.5" turn-out end cap perfectly and feels well-built.

The welded nut inside the insert is a real improvement—no more fumbling to keep the old bolt aligned while tightening. It clicks into place on my RS-4 turn-out and the USFS approval gives me peace of mind for trail riding.
