muffler -> scarf, by definition:
muffler (n): a scarf worn around the neck
However, I should also point out that I've seen "muffler" being used to describe a sort of short cape, to differentiate it from "scarf" (as a long piece of fabric that you wrap around the neck). This usage might stem from the armor item in ragnarok online, examples post #380680, post #377452, post #197517 and worn by Konomi in post #214706. Though clearly, this usage isn't common here, so I don't think there should be any problem with the proposed alias.
