Does exactly as promised
I run a full system Yoshimura carbon exhaust. The large plug I bought goes in two rings. It fits fine but Im thinking I maybe should have gotten the smaller one. Either way it works as promised. On a side note find a streamer or some other indicator to help you remember it's on there. I >personally used a "Remove before flight" tag I had extra. Wait 30 minutes before you install it when you shut down. I've heard other riders saying it will melt on hot exhaust. That's second hand knowledge though. Results may vary.

Does the job.
Works great and isn't pricey at all.
You probably want the small size (these are big).

had to modify to fit
I had to saw off a couple rings from the smaller end to fit my yoshimura exhaust, but otherwise does what it says on the tin.

Perfect size for Ducati Termignoni exhaust
I bought the large version for my Hypermotard and it fits perfectly. A number of these plugs are available and numerous people have asked for dimensions as few of the manufacturers provide them. Here are details for the large version of this Bike Master version for anyone wondering; 10 fins, each approx 1/8" thick with a 1/8" space btwn fins. O/A length of 10 fins is 3 1/16" (78mm). Diameter of the plug fins from smallest to largest; #1- 1 3/8" (35mm), #2- 1 7/16" (37mm), #3- 1 9/16" (40mm), #4- 1 11/16" (43mm), #5- 1 13/16" (46 mm), #6- 1 15/16" (49mm), #7- 2" (51mm), #8- 2 1/8" (54mm), #9-2 1/4" (57mm), #10- 2 5/16" (59mm). All measurements are approximate, taken with a plastic caliper, as are the mm equivalents. My Ducati Termignoni pipe is approx 1 7/8" (47.5mm) diameter at the tip, and this plug goes in with a slight twist to fins #7 and #8 due to the angled slash cut of my pipe. The material the plug is made of feels like a flexible soft plastic rather than rubber so is a little stiff, which is the only reason I gave it a 4 star instead of 5. It is still soft enough to mold and seal to the inside of the pipe as expected and is perfect for its purpose and price. I bought this model because it is brightly colored so I can't forget about it once I'm done washing the bike.

Not sure they're worth it
For one, the larger four-stroke version was way too big for my stock pipes on my '77 suzuki gs550. I wish they had just given actual dimensions than saying four stroke or two stroke. I just went to the hardware store and got rubber corks for 99 cents each and they work just as good, if not better.

OK Plugs
This would have garnered a higher rating if the rubber was flexible enough to fit snugly in the exhaust, but the fins were too rigid and one was too big and the next too small, so I had to file one of the fins to get a proper fit. I probably won't buy any more of this brand, I could have turned a wooden plug on my lathe in less time than it took to adjust this plug.

Sizing is very misleading
I was very nervous about buying the large, but the description said it was for most 4 stroke applications. The smallest ring on the large is too big for my Triumph Street Twin. I'll do what they should have done, and tell you that the smallest ring on the large size is about 1.5" and goes up to a little over 2"
If I could have just measured and purchased the correct size, I'm sure I would have been happy with this product.

To protect the catalytic converter and engine.

This is a better product than what I'm using now, basically a cotton rag that gets soggy anyway when washing off the bikes. Also the large fits my bigger bikes exhaust.
