I don't know much about their new e9x lineup. This morning in a conversation with a few other enthusiasts, this company came up and their former name was Streamline. I don't know the whole story but have heard that they were banned from M3Forum for some reason. There are a few CSL airbox CF trumpet failures when I did a quick google on Streamline M3 so YMMV.
Their claim for 12WHP is interesting with a stock intake/filter.
