Took me a lot longer than you guys. I should have come here for some research and tips/tricks first. Then it would have gone smooth. But oh well. I will go back and see how things are doin under there when i install my new tunnel plate. I love the sound of headers on a car....

Where did you actually punch/drill the holes? Did you do it just above the 02 sensors?
Any pictures?
My 02's sensors/wires are barely touching the tunnel plate! Thats why I am thinking about drilling the pass thru holes above the sensors...........

I marked the tunnel plate with a sharpie above each O2. I then removed the tunnel plate and hole sawed 1.25 inch holes in the plate (you need a large hole for the connector to pass through). There is probably an inch of space in the center between the plate and the torque tube so you could carefully drill it with it in place, I don't like drilling large holes upside down under my car so I removed the plate. Sorry for the late reply.

I marked it right above the O2 wires and then used a 1-1/8" hole saw. I then passed the O2s in from above. I also used a split piece of fuel line as a grommet so that there is no way that the wires can get abraded on the edge of the tunnel plate.
Attached is a picture.

What a great idea, the top of the O2 sensors and wires are touching the tunnel plate and I was worried about engine movement damaging the sensors/wires.
Now I will have to lower the headers again.......and cut the holes.
Also, I wonder why the O2 bungs are set across from each other at 45 degrees and not offset. The post cat O2's slid forward or back to get some seperation.
I sure would like to some pictures of an install showing the a complete exhaust installed.

Actually my fronts are offset. One, the passengres side I think, is slightly behind the other side.
I am not going to install the rear 02s. I bought some plugs and I'll just turn them off using EFILive.

I found a pic from my old install - it's just the pipes all laid out pre-install, but my rear 02's are offset - check this out, and everything is pushes together just like they were installed:
Is it possible to reverse a pipe since is would change the position of the bung?

Thanks for the pictures.
VortecC5, in that picture, the driver header does not appear to be in position too me. My sensors are extremely close.......with both headers mounted.
By the way your car is awesome!

That is correct. The drivers side header is not in place. I'll take another pic once I get them both in place. I have not had time to finish installing.
Thanks for the kind words about my car. It is much appreciated!

I see the light at the end of the tunnel!!!!!!!!!
Tonight I drilled the two 1.125" holes to pass the front O2's through the tunnel plate. This should help organize the wires. Again, thanks for the pictures.
Need to get a friend over to bolt up the exhaust and put the top side of engine back together. Then test run.
