Works well.
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.

Works perfectly for keeping water out of the exhaust
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.
