2.25" is what I was thinking.

It is 2.25.....not sure weather that is ID or OD. if it is ID, 2 3/8 could be the OD.....i dunno though just a guess

definitely 2.25 its the i.d. of the pipe just replaced my factory exhaust. Just for future referance pipe is measured by the i.d. and tubing is measured by the o.d.
