Well... idk about that particular compamy, but those names, athena, emgo, and uni, are pretty cheap, as in cheap knockoffs. I run emgo pods on my 34's, but they needed to be modified, and I cant imagin the chrome on the any emgo cheap mufflers would hold for very long, athena gaskets, well... mikesxs sells a complete kit for the xs, and its pretty cheap, havent had any problems yet, but, just read somewhere the head gaskets are a bit crummy. vesrahs are better. As for the uni's, better than emgo's, usually a universal filter. I usually see them on dirt bikes.
If a website is headlinning these cheap replacement parts, ide be weary, but thats me. Like I said, Ive used those brands before, but they are very cheaply made. I would not buy something as important and obvious as something like mufflers for fear they might be rusty from the factory. But as a filter, sure. better than nothing.
