It plugs it up!

What can I say it does its job, it plugs the hole. I can say that the tag dangling off the end is really cheep, its almost like a stiff pillow tag. Other than that it works good!

Works the way it should

Works great! It was a lot bigger than i expected though. Only the first few ribs fit in my fmf exhaust.

Butt plug

this fits all butts to your muffler. (dont put in butt.... its just a plug for your exhaust!) love the Motosport tag too!

Olive Branch, Ms

Plug It Up!

These server their purpose. They are worth the money especially if you pressure wash your bike. Keeps the water out, plain and simple!

A must have

Nothing special about this muffler plug but it is definitely a must have no matter the brand.

Spark Arrestor issue

Useful product but it did not fit inside my stock WR250f pipe. I imagine for non spark arrestor models this would not be a problem.


i got 2 of these plugs for my 2007 crf250r dual pipes and they work great never have water down the pipe

A must have when power washing. Fits great and does the trick!!!

Excellent fit!

Got two of them for my 07 crf250r! The fit is tight and secure, never afraid of getting water in my exhaust when pressure washing anymore. A must have for any motocrosser!

Important piece to having a clean bike

I have a 450x with stock exhaust and it works excellent but would also work with most if not all aftermarket also.

Good overall

works great on both my tw200 and my zx6r. Have to use the tag to get it to stay in the 200 but for the price it does the job.

Plugs Are Awesome

Just got them today. Fit in my 2006 honda crf250r perfectly. The "Motosport" Flaps are a little cheesy but its all good

Over 6 years ago Location: Thornton, CO
A: It keeps any and all derbies out of your muffler system during trailering or storage. If you camp a lot it's a good idea to take these along for over night storage in the rough.

i bought some plugs that were too big, are these the right ones?

A: measure the diameter on the outlets of the pipes and if that measurement falls into this, 3/4" - 2.0", than these will work.
Q: What is the muffler plug made of, and would you suggest using them to plug the mufflers on a 2005 FZ6 to keep out moisture during winter storage?

A: It's a urethane type material. Yes it will help keep the moisture out during cold storage.
Over 6 years ago Location: Thornton, CO
A: These plugs are made of a semi soft rubber material. They would definitely keep moisture out during winter storage.
