Ok, I just got my downpipe Today. (September 20th) and I ordered it July 13th.
I did wait about a month before I inquired, at which time they sent me an e-mail simply stating that the downpipes were still "in production"
This info would have been more helpful to know when I first ordered, so I might have been more tolerant and/or patient and/or understanding of the long wait.
Anyway, I have it now.
And my car is still in the shop getting a clutch and other stuff, so in this case it's all good.
