I don't think going from 2.25 to 2.5 is hurting you, I think the exiting in front of the tires is "tricking" you, now you are hearing the exhaust from one side, not a fully balanced tone. Try a full tailpipe, it may "sound" smoother, balanced and maybe even faster! I did some actual drag strip testing on a car some years ago and went from a Dynomax Hemi muffler to a Flowmaster to the Magna flow, the magna flow produced the lowest ET's and the nicest sound.
