Review about the Exhaust plugs universal FMF №6314

I bought this thing once "for change", sometimes quite useful! I use when I wash my motorcycle, so that excess moisture and dirty water does not fall into the muffler! Also, I insert it into the muffler before wintering the motorcycle, the main thing then do not forget to get it before you start! :) But with this like problems there is no, to the same still amusing banner-a reminder there is!
