FMF Muffler Plug

Does the job. People are complaining about it not fitting in their exhausts but if they read the notes they would see that they may need to trim it.

“Notes: Check measurements before ordering; will not fit exhaust outlets smaller than 3/4". Trimming may be required for fit with 2-stroke exhausts.”

website says it would fit a 2020 crf125f but the plug is too big.

So I bought this not thinking I have a HMF muffler not FMF and it's a pretty big muffler so I just waited until it got here to see if it would work and it did it worked beautiful its awsome thank you

It doesn't even fit the FMF pipe I just bought with it

This muffler plug did not fit into my exhaust

Works great deals tight, however the nice remove before flight tag falls off in no time

I like this plug because it fits a wide range of bikes including both 2 stroke and 4 stroke. These have a very good fit in most bikes, including ones still equipped with a stock exhaust system.

Fits multiple size bikes pipes. Stays snug to ensure good seal.

It works like it's made to. The remove before flight tag is not made well and if you plan on leaving it in while driving to the track it will be gone before you get there like mine was lol it was the first time using it but still gets 5 stars because it does what it's made to do.

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