thankyou guys!.......nice writeups....ok e few more questions?I have an AC delete and no cats/smog pump.Should i get the egr delete gasket? also is the hole in the middle of the runners underneith the egr passage? and i have a few pix here.one is a weird elbow that came with the explorer intake and t-body i dont need it do i? When i took it off there were 2 normal bolts and 2 long studs....do the studs unscrew?,because the t body wont be able to bolt up with only 2 bolts......are they usually studs or did someone put the studs in and i must have a machine shop fix it?? I hope these are good questions and not lame?
