I just recently got a new(to me) Drz 400 with a full FMF exhaust on it which is pretty LOUD and I need to quiet it down. I have found a QUIET CORE INSERT on the Motorcycle Superstore website and looks like it should do the trick. So what I would like to know is if anyone has tried this out and secondly where can I get one locally. I have the Royal book in front of me but doesnt look like they carry it.
