I am sure you are going to have a lot of comments on here from much better experts than myself. I would probably go with the 2.5 and get a little bit of back pressure on it. I researched a lot when putting a exhaust on my truck and from what I experienced it seems that the Hemi likes a little bit of back pressure so going too big, will make you lose in low-end torque. There are many others on here that know much more than me though. Just from what I read.
