FS: long tube OBX headers w/extension pipes to catback
#11
The tube goes to the EGR valve...which I've removed on my truck and tuned out of the PCM. I think 03 and later trucks didnt have EGR to begin with, but because these are made for 99-06 they put the flange for EGR on there on the headers.
I think the fitment issue is a simple manufacturing error.
