How does it sound without running through the Cat. Is it obnoxious loud or just annoying loud? Annoying loud I have to get used to, obnoxious loud the neighbors have to get used to. Neither one meets California smog requirements though, right? But if it'll get me bye for awhile I'd be willing to run it like this, for awhile.
