Jimbo, in Florida got a "Prototype" BORLA that has round tips and a different resonator, but mine is the production version and it has oval tips.
Many of us wrote to BORLA requesting different tips and told them that we did not really want a round style.
We were sure they would not design a special tip but since the oval is used on other applications I guess that is why they chose them.
AND our voice may not have had anything to do with it but..............................
to my knowledge.....................ALL BORLA production cat-back systems have oval tips!!
