Put me down for one of each Snickers. I want a budget base header, as well as one with full merge collectors. I know you said you dont want to make them in 304 stainless but would you be willing to make one for me in stainless? I am willing to pay the difference. Also, I think you should try one of the full merge headers with a megaphone. I think you will be suprised on the power that can still be gained with a 4-2-1 megaphone setup.
For those of you that are probobly wondering how much power the full merge collectors will add and change the power curve... the formed collectors are very poor at directing the exhaust gasses as well as making low pressure areas. Both of these can greatly affect the power of the header in all areas and mainly the top end power band. I believe the full merge collectors can make as much as 4-6whp on the top end alone, and even more on the bottom end below 4000rpm.

Ted, I can do a stainless one but the biggest difference in price is in the collectors. I have one stainless flange left and I have plenty of SS tubing so that will only take the cost up by basically materials. The SS merge collectors alone will raise the cost by at least $300 alone so full retail would probobly be in the $1100 range give or take. I'm sure I can cut that back a bit because someone else wanted a SS one of these as well.
I do plan on trying to make a full merge header this week and possibly re dynoing it vs the base header.
