Pacesetter & OBX make LT headers for 2wd & 4wd, on Pacesetter the part numbers are diffrent for the 2wd & 4wd models. OBX headers might also have diffrent part number also for 2wd & 4wd. I'll be ordering my headers for my 06 4x4, I let you know how it works out.
On ebay it says OBX headers will only fit the 4wd model so you would need a diffrent part number for 2wd OBX.

[/QUOTE] Best headers on the market come from American Racing and Kooks hands down!! However, they dont make headers for our trucks. Dynatech is up there with Kooks and American Racing in terms of quality. The price posted up above really isnt that bad for a set of Longtube Headers. I paid way more than that for the LTs on my vette and GTO.

Those aren't cats that come with the OBX's, those are resonators. You will need to trash those and buy the Magnaflow cats.

There's nothing wrong with the resonators, but it deletes the catalytic converters. It depends on individual state laws, but deleting cats could make your truck illegal. It's illegal here in Louisiana, but I have yet to see anyone look under any vehicle for the annual inspection and we don't do emission testing.... yet.
