I want to plan a mod (my first for this car) and am reading as much as I can about dual exhaust on the V6. It sounds like Flowmaster AT or Flowmaster 40 is well liked here. I'm looking for a recommendation for an exhaust shop in Tempe, AZ area that has solid experience in doing this. While possibly within my skill set to perform, I'd rather have someone else do this as I'm stuck working long hours for the next several months.
