So I was bored and decided to give Berk a call. Spoke to Lauren. She told me that it looks like a further delay. She didn't know exactly why but she said it looks like July now.
I suggested to her that they (Berk) email everyone who is on the waiting list with this info. She reacted like it was the best idea ever and said that she would pass it along to the sales department.
Now I am not sure how long Berk has been around but I do know this isn't their first time making exhaust systems. It is possible that they don't want us to know the exact reason for the delay because they don't want to lose our business. I have to admit that I may start looking at other options if we don't get some reliable info by the end of the month.
Looks like I have to update my sig.
