Craig,
Crash needs time with 04 since these guys are still trying to figure out the other issues with the 03s. I`ll give em 15months for any 04 response

Congrats on your H2!
BTW...That popping noise has something to do with heating and cooling of the Cat or Muff.
Samething happens to most 03s, including mine
