Hey, I did a bunch of searching, a lot of reading, and I still can't find the specs of the D-series Performer X manifold, mainly the runner I.D. Is it larger than the stock manifold runners in I.D.?

There are plenty of dyno results and discussion, but I came up dry on the size/specs for this one, B-Series is covered in great detail though.

If anyone has a D-Series Performer X and could measure just the height and width that would be a great help. Anything else as well, overall length, plenum size, etc., etc., would be a bonus.

Thanks.
