yeah, Stromung stopped doing group buys (I think they had a hard time with one of the last ones). The problem I'm having is, it's not just people asking for cat-back systems for their car. Some want just the mid-pipe and some need custom sizes and some cars aren't in production yet, etc. and there are a million and one questions I have to find out.
but I do have a little help...M.Young has a good connection with Stromung. I have a guy on the Sr20de fourms that has been in contact with Mossy, and Fredro from the b15 forums is going to help out too. hopefully it'll stay on a smooth track for now.
