Default Is there a 3" inlet x 2.5" Outlet X-pipe?

I've heard lots of folks talk about this but have only heard of one mentioned by name (Dr. Gas). Does this really exist or do you use a reducer to get to 2.5" outlet?

What benefits does this give over the 3"X3" X-pipe if any?

It exists.
This article talks about it. See #5 on their "Recommendations" list.

Benefit is simply for added clearance beyond the junction, whether going over or under the axle out the back.
If you're gonna dump before the axle, 3"x3" is the way to go.

My intentions are to have the pipes exit in front of the rear wheels, so then a 3"X3" would be best. Will there be significant rumbling and noise inside the truck?
