I am using the jackson header, I am quite happy with it, however the DC seems to be the better choice. toda is well respected and performs well, however it is the most expensive. I know you can add a race cat to the jackson, not sure about the DC, and I am certain you cannot add one to the Toda. (correct me if I am wrong).
On balance I would think the DC would be the one to go for as a balance between cost and performance. I am sure on the road there would be little to tell between that and the Toda.
