  1. 8-4-1 Headers (Video)

    I know the design was revised a while back and was supposed to push the pitch higher, but it seems like those changes completely altered the tone—and not in a good way. This sounds muted and kind of lifeless compared to what we were originally presented with. Also makes me wonder—were the...

    I hate to say it, but… this sounds really off to me. It’s not even in the same ballpark as the original clip we were shown. I’m wondering if the latest revisions to the system completely changed the tone, because what I’m hearing now is not what sold me on it in the first place. Honestly...

    You’re really about to make me unpack seven boxes of metal—two of which look like a stainless-steel intestine puzzle—lay everything out like I’m prepping for an autopsy… and then somehow repack it all back into those perfectly foam-imprinted slots like I work for NASA, huh? šŸ˜… You already know...

    THE EAGLE HAS LANDED.!!!!! …buuuuut let’s just say she didn’t exactly stick the landing without a little drama. First off — credit where it’s due. The fabrication work is seriously impressive. The welds are clean, consistent, and look like they were laid down by someone who actually cares...

    My kit officially shipped out today… and yeah, I’m way more excited about this than a grown adult probably should be. As soon as it lands, it’s going straight to a buddy’s shop — no ā€œlet me admire the boxes in the garage for a weekā€ phase. We’re throwing it on the lift and getting right to work...

    I’ll reach out again and see if I can get a fresh update on this elusive setup. Last word was March–April, so maybe we’re finally about to hear some Voodoo symphony. With any luck, the wait pays off big in both tone and performance — really hoping the juice is worth the squeeze. I’ll share...
