hey if you want to buy some i just took off mine to put my turbo setup i can sell them to you... its going to be a direct swap from your stock headers they were on my K8 before and on my klze about 2 weeks ago...

They are the ones that don't have the curly Q under the oil pan, or flex tube. They have to be cut and redone. No way around it :(

mine does have the curly Q under the oil pan and it does have the flex tube and its still not lining up (not to mention its hitting the oil pan and my shift linkage)...so im thinking im still going to have to cut it and weld...i just dont know how to go about getting measurements and what not to do it...seems like a difficult process...any ideas?

With those, most of the time, you do have to cut a few inches off the end, and weld it. You can dent your oil pan a little with a hammer, holding a piece of wood against it, or those round pieces of metal that body men use. If it fits under the oil pan, but is tight, you can run the car until they're hot, and bend them away a little. They are a few inches long at the flex tube, because the Probes are longer. I would recommend that you cut off the flex tube, and weld in a ball and socket joint while you're at it, if you have the ability. That will free up a few more HP (up to 7, I believe).
