I am pretty sure your right because I measured it before and I don't think it was 2.5. However, Ahmed on JC.com had the 2.5" installed lol

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.

Thanks for all of the info man. I ordered the 2.5 I/O today. I can't wait to have it installed!
Awesome, can't wait to hear it cause i've been debating what muffler to have ready for my "backup" after i tear open the stock one on a rock!
High fives for the Phillies sticker.
Its not really an "if".... more of a "when" it happens. The stock muffler is huge and hangs down pretty low lol
Last night I rotated the tires on the XK and crawled underneith to check everything out for tomorrow's off road trip. I noticed a nice size dent in my flowmaster muffler. If i still had the oem muffler im pretty sure it would have been destroyed. I love the flowmasters because they are very thick and act like a skid plate!
