I've done this experiment several times on back to back (within a few minutes) runs on different nights and the resuts are very consistent, .12 and almost exactly 1 mph. I still have the factory catback. I haven't had the car tuned yet.
I just picked up a Loudmouth II catback but haven't out it on yet, I'm curious to see how it performs compared to my catback.
