alright, I bought this piece off of Glenn (rb s14) thinking all 3 bolt downpipes are the same. keep in mind i have a s13. i was trying to bolt up to an SR o2 elbow, and was unsuccessfull. The flange on the downpipe looks like it has but cut, rotated, and welded back. I was told that this is what is needed for it to fit on a s14. It is an old greddy down pipe, and all i want is what i paid for it, 40 bucks. lmk
