SPARK ARRESTER KIT RS-12 Muffler, 1.375" (SA-20-K)

Quiets down the RS-12 on a DRZ-4S

Quiets down the exhaust just a touch more than the one included one did for the 2025 DRZ-4S with the full RS-12 System, probably not quite out of earplugs on the highway range, but it is a noticeable reduction in volume, but the bike still sounds great

Best choice for a Quiet Muffler

I bought a RS-12 slip-on for my 2024 Honda Transalp. A really nice piece. The standard slip-on is pretty loud. Not quite open pipe Harley loud but getting close. So I bought the smallest I.D. spark arrestor with screen. It still has the deep tone at idle but it's a good DB killer, just a tad louder than stock. I think the next size up would be what most people that want to modify their exhaust would like.
