If that is the exhaust i am thinking it is, then it is 2.5" to the flex section.
Now you have me second guessing myself? I am still about 99% positive that at the o2 housing flange it was kind of cut and crushed to 2.5" and the problem that I had was that the o2 housing studs were the same width as the 3" tubing.
Either way it is free and has a brand new o2 sensor in it that could probably be sold for something.
