OBX Header Install for 2004
I just bought a set of OBX headers and my friend (who done 95% of the work) and I installed them. Had to remove valve covers on both sides, on the passenger side header it took us having to take off the starter and leaving the header loose to put the starter back in. That was the hardest part of the header itself, install wise. The driver side header took unhooking the string ground band and another wire grounded at the same spot. We also had to take the bolt out of the steering stem to get it out of the way. After we got the headers in and set the header mounts did not line up to the original mounts so we had to fab a bracket and weld it to the original mounting bracket to make it work. After that, you will need extensions for the 1st set of O2 sensors. Another problem with the first set of O2 sensors is that the mounting hole for the sensors themselves face almost straight up into the driveshaft underbelly cover. We had to remove this cover and modify it to even get the sensors set. Ran into many problems with install and waiting on extensions to finish job, I'll keep it updated. Anyone else went through the same problems?
