i have a set of bbk long tube headers for a 99gt and was just wondering what and or why there is only one bung on one of the headers. is there only one o2 sensor prior to the h pipe or what is the bung for. also can anyone tell me if i will have a problem installing these long tube headers on an automatic. the headers are bbk-1541. thanx

the bung you are looking at is probably the one for the EGR. there should be 2 more holes for the 02 sensors.. i don't believe they will fit an automatic, only the hookers and mac's will fit auto's as far as i know..
