Borla XR-1?

Quick question. I'm considering changing up my exhaust setup (one final time hopefully).

I have JBA long tubes, catless bpipes and an MBRP Pro Series 304ss catback. I was thinking of swapping out the muffler and tip in favor of a Borla XR-1 with a dumped tip over the axle for a cleaner look and a deeper tone.

My question: Is there any difference in sound/performance between the oval (40944) XR-1 and the round (40085) XR-1? Both are 304 stainless, and both are single 3-in/3-out. I was under the assumption that shorter mufflers will be louder. That being said, the oval is listed as 16" x 4.5"(narrow part of oval) x 7.88"(thick part of oval), and the round is listed as 15" x 5" diameter round.

Any thoughts on differences, or anyone with firsthand knowledge on either one? I don't anticipate space will be an issue, so no worries there.
