Here are some pic of the Advance Adapter Header and the L&L header previously mentioned:
Really the only dif I can see is one is a flanged header collector and the other is a slip fit in design and one set dumps to the front on drivers side, suppose that is better for 4x4 setup, I do really like the big tube primary on these headers and thicker header flanges, makes it easier to control a leak, more plate there in case you need them surfaced, but with the thinner flange like on the Patriot I will just cut the flange between exhaust posts, this allows a better seal as there is no strain between ports on the flange, problem for me is with the AA and L&L headers they don't mention fitment using an AOD trans in their descriptions (at least I didn't see anything when I was reading the application notes) and unless you running a forced induction system (Blower, turbo or a power adder like NOS or Methinol fogger also know as snow) the larger primary tubes will hurt by slowing exhaust gas flow witch in turn will reduce torque at lower RPM's but will help at higher RPM's where these little motors make their best hp, just depends where you want it, as for fit up I am sure they work fine with C4 or std with small bell housing. If using a set of mechanical dump valves it would be difficult to set-up with this configuration.
The AD headers go for about $275.00 and the L&L are around $500.00 before shipping (PRICES ARE FROM THEIR MANUFACTURER'S SITES AND MAY VARY FROM SITE TO SITE). I paid $223.00 delivered to Canada for the Patriot Tri-y headers, if they don't work out power wise I will upgrade to something better in future but for now they suit my purpose and pocketbook. With some slight mods to my Ti-y headers they fit great and I can remove them from inside the engine bay.

Here is a good shot of the Patriot Tri-y headers installed on a Ford Ranger V8 windsor conversion with a std and small bell housing where no mods were required to the headers, the builder took this pic with cab removed, great shot thanks, I forget which thread I got this from and sorry for not giving credit to actual owner if you see this pic and it's yours, first off thanks for posting it and please speak up so I can attach your name and a link to the picture for the original thread I got it from.
