Muffler Exhaust Wash Plug, Coitak 0.6"-1.5" Wash Plug for Motorcycle Bike 2 Stroke Rubber Exhaust Silencer (2 Pack) (0.6"-1.5")

No issues with fitment on stock TX300 silencer. Measure your diameter and you'll have no issues. The rubber is only slightly stiffer than the FMF version. For the price and the quantity, it's a good buy.

As a moto mom with bikes getting washed almost every weekend after the track, this little exhaust wash plug has been super handy. It’s one of those small things you don’t think about until you realize how important it is. The plug is made from thick rubber and fits snugly in the exhaust, which keeps water, mud, and debris out of the pipe while washing the bike. That’s especially important on two-strokes because you definitely don’t want water getting into the exhaust or engine components. I like the tapered design, because it fits a range of exhaust sizes (around 0.6"–1.5"), so it works on different bikes in the garage without needing multiple plugs. The bright “remove before ride” style streamer is also helpful—it's a good reminder before starting the bike so you don’t forget it’s still in there. Installation is about as easy as it gets: just push it into the muffler before washing the bike. It stays in place well and pulls out easily when you’re done.

I use this on my dirt bike when washing it and it does exactly what it’s supposed to do. Fits snug in the exhaust and keeps water from getting inside, which is huge if you’re trying to avoid issues after a wash. The rubber expands enough to get a tight seal without being a pain to install or remove. I’ve used it multiple times now and it still holds up fine—no cracking or loosening. Simple product, but definitely worth having if you wash your bike regularly. Way better than trying to stuff a rag in there.

They work decent for the banshee, the rubber is a little stiff, I have a hard time getting them to stay inside the exhaust.

Works great. I wish I got the smaller size of the two for my YZ450F and TRX250EX though. The larger size fits, but barely. The material is rubber and flexible and the added remove streamers are a quick reminder and draw attention. Value for the money is spot on!

It works but barely fits the stock exhaust of a 2026 YZ250F.

I got this for my 2026 Yamaha YZ250x 2 stroke and it has the stock silencer (Its about 1 inch in diameter). Its a really tight fit and the rubber/plastic is really tough to get in there to get the proper seal that its intended to do. I ended up getting the FMF wash plug it works way better and its softer to work with. This plug doesn't really work for my bike but it may work on yours, the real question "is the price worth the gamble".

They work as advertised just make sure you know the size of your exhaust

As expected

想像してたものより小さくて使い物にならなかった

I paid almost 20$ for 2 pack of these and found them on amazon for $6 a week later for 4 of them, not to mention they are made of a hard plastic instead of something softer that would push inside of the silencer. Save your money.
