My friend just bought a 2006 Hemi XK and installed MBRP 3 inch Cat back exhaust. His oem exhaust was 2.5 inch, the same as my 4.7 Liter. The reason it looks like slightly larger than 2.5 inch is because your measuring the O.D. of the exhaust but it goes by inner diameter where the exhaust flows.
Unless they changed the diameter for the newer XK's. Wouldn't make sense to me.
