Jeremy has kindly informed all the preorders that there will be a delay. It isn't fun, however it is great to see a vendor work with their customers and keep them informed.
He sent us an except from Borla. My main takeaways
+No one who preordered will be getting the older possibly inferior design
+it is good that Borla decided to make this change before their first batch as to not proverbially "shaft early adopters"
+it will be about a month of waiting
+No details on what design changes other than to "Improve the performance and reliability of this part"
+I didn't know this but Borla designs and manufactures everything in the USA
I'll let Jeremy have the honor of posting the excerpt
