Welp, one week later and I just called Stillen and got some strange news.
The "customer service" rep I spoke with said the last time he was update they told him 1-2 weeks. He didn't mention when he was given that timeline.
He then said he isn't sure what the current estimated wait time is.
I asked him if there was anyone around that I could speak with who may have more information and he told me no one really knows, including the team that assembles everything, because they're waiting on outside suppliers for certain parts. Apparently the supplier doesn't work on any sort of timeline or provide Stillen with any updates.
Essentially he told me no one at Stillen has any idea when the parts to make the intakes will be sent to them, let alone when the intakes will be built, assembled, packaged, or shipped.
What a frekkin company...
