Hmm, just seems like he said it was at the dealer waiting for the Stage 1 to arrive though. Which would to me indicate either it had the stock exhaust on it still, or shipped without any, which would be a bit odd.
When I order mine I'll ask the dealer what's up, as I wouldn't mind having the stock exhaust for getting jigging alignments set up while having a functioning exhaust still on there.
The dealer took a photo of mine as it was being unloaded from the shipping container and it had the stage 1 exhaust installed.
