I can understand that, bending the pipe is easy. Making a New Tip design is something else. A lot more enigneering and cost, I don't think any of Borla existing tips are oval what they call oval looks round to me. Bassani makes an oval tip that would work. But I don't thin they make their own tips probably an off the shelf product, Borla on the other hand has their Name on "stamped" on them Its either made by or for them - which takes longer. If Borla makes an oval tip I might change. But I like the round too, looks ok.
