Sorry for the lengthy silence. I have been out of town...
I picked up the truck last Thursday. They showed me the headers rough tacked but in final shape. Not sure when production sets will be available, but should be 6-8 weeks. The dyno tests will be done before and after the final install so no results yet. The designer said the passenger side was easy and the driver side more challenging due to the steering as everyone predicted. They had to run one tube high to give the clearance, but seemed pleased and agreed that the stock headers are a joke. I will let everyone know when I hear from them again.
Any comments on installation?
