Id go oval case for sure. Because I currently have a circle, and I swear the oval sounded better.

But serious all Borla XR-1 sound great no matter shape. Iv had tons of them, and i honestly cant say if theirs any for sure difference in sound.

Techincaly circle case is suppose to be a little raspy/louder than oval.
