Exhaust is done, car is fully tuned with the fmic. Its great!
And to anyone who said it lags more, well, not by any significant ammount . From a 2500 rpm roll, we had 19.5 psi at 3200 rpm. From a 4.5k roll, its near instant. You should see the heat difference too. I did 5 pulls last night, then pulled into a parking lot and let the car sit for about 2 minutes, while running, with my hood closed. I then turned off my car, poped the hood ,and felt the hot side pipe. It was hot enough to burn you. I then felt the cold side pipe, right at the TB, and it was cold as ice 
So, yup, it works!
