This isn't cart before the horse. The headers in the pictures are a customers set that were sent to us to as they were dissatisfied with the design and build quality and wanted to see if we could come up with something better. While they are a good start, they leave a lot on the table regarding the fitment and overall design. We could test these and post performance numbers but that would do nothing as the ones we make will have several key changes and will perform differently. And as for fronting money for R&D, 10 deposits doesn't even cover the costs of putting together the first set for testing. It's more of an indicator of those who really are serious about purchasing them knowing that while they will produce power, the extent of that power is unknown. And this isn't a bash at those that don't want to be part of the R&D on these, it's just that with this being such a limited market, we need to have a hard and fast number of people that are in on these and not going to back out.
