Yep, Wade is building. I spoke with him yesterday to ask him to notify us when he is getting close to completing our order so we can contact everyone who has placed orders for headers. As an aside here, I also let him know how many 5 gen vs how many 6 gen orders we have. To us VFR owners, the only difference between 5 and 6 gen headers is that 6 gens have a 5/8” shorter collector exit pipe, but, to the builder, there is more to it than simply chopping off 5/8” from the finished assembly. Because the mandrel bending machine clamps so hard on the tubing to bend it accurately, the tubes suffer slight deformation at their ends. So Wade uses a hydraulic machine to expand the ends of tubes to the correct diameter. What this means for the collector exit tube is that he needs to cut off the 6 gen’s 5/8” prior to expanding the tube in order to provide a long enough expanded section to provide the proper length of clamping area for the midpipe to be fastened. I like that our fabricator builds our headers with this amount of foresight and experience. Back to the topic at hand - Wade has all the tubing back from the mandrel bender and is ready to start welding, but his supplier of tubing merges is backordered - one of the ways he keeps our cost so far below other fabricators we contacted is by using pre-manufactured tubing merges made from the same quality 304 stainless steel as the tubing used for the headers. The supplier told Wade he will have the merges for our headers by January 18. I and Duc2V4 both apologize for the delay - it certainly has taken much, much longer than expected to get to this point. We will stay in contact with Wade and, as we get them, will post more updates here.

As stated i have no RB anymore or PC for that matter, and is not tuned, so there is definitely more to be gained. However, it's not all about that top hp number, as other graphs have shown its more about that midrange, where road users spend the majority of fun time in.
