You most certainly do have secondary's (I have the same car). I'm not entirely sure about the RWD N55's, but the xDrives do.
I have a BMS downpipe with the stock catback. Sounds good. If you're into a more conservative sound, shoot for this.
Coming from a straight-piped WRX though, it's not loud enough for me. Going to get my perforated pipes replaced with straightpipes ASAP.
