[SPOC] XRC problems, please respone ASAP

[Ostrix]

This is not a flame, merely exactly what happened in my specific case.  Please, write back.  I was supposed to have my car ready for my show this weekend, so I ordered in march.  Ok, here're the details:

I ordered my XRC throttle body late march (either 2 or 3 weeks before the April 6th show) and got my throttle body 2 weeks ago after MUCH calling and hearing the same old story that they "forgot to send it, and it'll be out tomorrow."  Then, today I get what is supposed to be my 2.5" cat back.  I get everything ready for the shop tomorrow, and my exhaust doesn't fit the muffler!!!  After waiting almost 2 full months, I am short one throttle body core refund, and 1 exhaust system.  The small inlet on the pipes measures 2 1/8" and the larger end is 2 1/4".  NO WHERE does it get to be the exact 2.5" that my Dynomax (which JEGs shipped to me in 4 days) muffler is.  Has anyone else noticed these qualities in XRC's customer service?  Whenever I called, I never really got a straight answer and now my deadline is pretty much passed.  main things I need to know:

Is the XRC 2.5 inch cat back usually short up to 3/8" in diameter?  

What I have is between 2 and 2.5 inches, what do I in fact have?

Should I just get everything else I need from SPS from now on?  They seem to be of a higher quality.

I plan on getting a turbo, should I just see if the shop can just adapt my whatever-the-hell-sized tubing to the muffler and go with it?  Or will another 2-3 months of calling and waiting be worth it to finally get the product I ordered?

Truely frustrated to wits end,
