I have the same headers. I measured and it looks like they need a 5" offset to the pipe. I plan using the offset extension pipes like I mentioned earlier on this thread. My exhaust is 2.5" so of course yours will fit a little different. Anyhow, I'll have to do some cutting an welding probably and a little bending also. I plan on using the collectors that came with the headers and welding the extensions to them. I plan on cutting off the Flanged end of the extensions so that the bendis as close to the header as possible. If all else fails I'm sure most muffler shops could fix this problem pretty easily. I have a couple pictures here to show you we're pretty much both in the same boat. Good luck!
From the end of the header to the x member is 7" . I tried to hold the tape measure up and take a pic at the same time so it's not perfect, but the offset is pretty close to 5" to have it centered on the cutout area of the x member. Pics are with collectors temporarily in place. Let us know what you end up doing. Thanks Steve
