FMF Muffler Plug

It’s for a four stroke not a two stroke but it should still say (ONLY FOR FOUR STROKES)

I bought this about a week ago. Upon looking at it i immediately knew it was going to be to big i barly could fit the first ring in the silencer

Did not fit my YZ125. Overall it was a nice quality though!

reminds me to remove it :)

This doesn't fit in the stock exhaust of my 2018 Yamaha WR250F. I bought it because I thought the "remove before flight" tag looked cool. Turns out, it's pretty junky plastic and it has red paint chips falling off of it. It's only $5, so it's not worth returning. I guess it's going in the trash.

Fits like a cork. Tag is basically a piece of paper so just like ecerybody else states...I’m with them about not pulling on the flag. I basically ordered this one because it was the same price as the other basic plugs but I had to see the tag for myself.

Keeps the water out of my exhaust, work well

Fairly explanatory product. Put this in the end of your four stroke exhaust to protect it from getting water in the exhaust when washing the bike. As other reviewers have indicated, the red flag is not extremely strong so do not pull on it to remove the plug. The flag is there as a more obvious reminder that you have an exhaust plug installed. How many times have you seen someone who is having a hard time start their bike when they realize the exhaust plug is still installed :) The ribs on the plug make it easy to push in and ensure you have a snug fit before washing your bike.

Was way too big for my son's KX65. It does seem like a good quality rubber plug though.

Very well constructed and adaptable to many exhaust sizes by simply trimming . Forget about pulling on the little red FLIGHT TAG to remove them from your muffler , they just rip , I think this is really just for show . I never pulled them that way . However , I did put a zip tie to hold them on , but never the less they flew away while I was transporting my bike via my pickup at highway speeds . Oh well .
