I talked with the designer for quite a while. The one on Alex's car is stainless, one on the wall is TI. Alex just got his car, so they really have not done any testing yet. Looked nice, however the tips are a touch busy. Sounds like they are going to make the stainless one for sure.
SEMA Borla GT looks great. from their Face Book Page
