I have a set of headers that I got out of the back of another firebird just like mine, I have no clue if they were on the car or if someone just was using the car for storage.

but I would like to use them on my 1991 firebird, but its a daily driver. so I can not afford any excesse down time from my car. I dont want to go the through all the hassle and find out that they do not fit.

the only numbers i could find on the headers are 6831 10 01.

but i think that the headers are these ones, they look exactly the same.

hopfully someone on here knows for sure if they will fit.

If they look exactly like the ones in those pictures they won't fit, the K member is going to be in the way. The ones made for your car have the tubes all angling towards the rear of the engine when they come out of the heads, not straight down like the ones in those pictures.

 

ya man that sucks, the headers look like they will fit. i dont want to try and find out they dont, the headers are so small they look like they are made for camaros.
