Fantastic CAT. No more odor

The car feels almost the same as when I had the test pipe. A retune is pending but this has cleared up the smell and I no longer get to work smelling like dirty exhaust. It was shipped quickly and they dealt with my multiple calls for clarification without getting annoyed lol. STM is great.
