i'm currently going through this issue as well. the primaries hit the firewall in 2 places, and the 02 sensor hits the floor board. the driver mount is new, and the passenger mount shows hardly any movement when i torque the engine in reverse, but i'm still going to change the passenger mount before i escalate the situation with them any further.
to minimize contact in the meantime, i used a dull prybar and a hammer to persuade the sheet metal not to contact unless i give it some decent throttle.
on a side note, having to buy angled plug boots to prevent them from touching the ******* primaries would be great ******* information before buying the headers.

I pulled the heat shield in your last picture. No hitting.
As far as the O2 sensor I plan to remove the drivers header and beat the **** out of the floor. There isn't enough room to do so properly with the header in. As pictured with the modded sensor it doesn't hit unless I FLOOR it in 1st. Otherwise no contact. Its still damned annoying when it does hit.
Agreed on it being nice to have info about plugs and primaries. I also agree there should be changes made to the part.
Worst case scenario I weld in a new bung and plug the stock one. I have the parts ready. I'd rather not subject my headers to my welding skills though.

UPDATE:
So i replaced the right side motor mount, removed the left heat shield, and smashed in all the prior points of contact with a persuasion tool. It doesn't make contact under acceleration anymore, but now it actually rests on the frame with no load.
Somebody seriously fucked up on this batch of headers for the left side, and they refuse to admit it.
Also, the Y-pipe is too long where it meets the collectors. So you either have to cut the collectors or remove the transmission crossmember! This is the most poorly "engineered" set of headers I've ever purchased. I'm having V-bands welded in for the collectors next week too, because the slip fit connectors won't clamp tightly enough to stop leaking. They told me to buy grade 8 bolts and try again. **** off.

Get these clamps.
