    Looking for the stock O2 housing (1g and/or 2g) outlet stud spacing. I haven't had a stocker in a while and I forget what the spacing is. I'm thinking about a downpipe project and it would be useful to be able to revert back to stock if necessary. Thanks in advance.

    Paul, we talkin' about essentially the flange on the downpipe that mates to the O2 housing? If so, I have that laying around somewhere and I can measure it from bolt hole to bolt hole. Will do tomorrow though as it's half past midnight as of writing.

    Downpipe bolts appear to be 3.75" spacing. O2 housing flange pics for posterity.
