Hey Balz!
I checked out the SDJ 12a header on their website, and I have a few questions....I'm glad you have experience with it!
First, what exactly makes the power on this header? Second, is the diameter pipe appropriate? What diameter is it? And third, do they grind the welds on the interior of the pipes as they construct the header? Or are the welds and related bumps unimportant in the Hp search?
Do you think this header produces more Hp than any other? A good comparison might be the unbiquitous Racing Beat design.
I ask this not to challenge, but as an interested future header buyer. I currently have the ISC header, which is a very pretty stainless steel affair, similar in appearance to the RB unit, but I'm unsure of it's position in the big picture, Hp-wise!
Thanks!
