So far I have unbolted and cut out the the oem manifolds and Y-pipe, cleaned the heads with emery cloth and installed some BBK O2 extenders. I have also purchased some Stage 8 locking header bolts along with fresh O2 sensors and some Ford Racing header gaskets made by Fel-pro..I'm still contemplating an EGR delete if the tube doesn't line up with the headers. I also had my X-cal 3 tuned to eliminate the rear O2's since the OBX kit doesn't have the rear bungs as well as parameter changes for the front O2 locations. What I really would like to put out there is how is my truck going to run on a virtual open exhaust system? I only had my original cats to quite things down and after the Y-pipe is a 3" straight pipe exhaust with a Magnaflow tip...that's it, and the OBX kit only has resonators behind the LT's. Should I consider a performance muffler help with the scavenging affect of the exhaust pulses??

I vid will follow shortly after I install the LT's...I'm sure it is going to be loud and obnoxious.
