That is the opposite of what I said
but I understand you don't want to add more cost.
It's a shame you did not put the headers on first. Roughly 1/2 to 2/3rds of your HP gains are from headers alone, so I'm guessing we can expect 10-15hp from the system you tested; with a tune adding a few more ponies.
If someone from the group buy can do dynos before/after with headers it would be appreciated
