Good for you! I also think a well managed race from a slow roll is a great way to visually see the differences from various states of tune. The mountain drive however, way too much driver skill involved there to assess the car performance. Have a great time this weekend, I envy you the good weather and the driving terrain.
Yup there are cats in the stock exhaust. Check it out.
