My BTG exhaust is great, I was considering the 3" before I bought my BTG, but I was told that the Turbo needs some back pressure for the motor, so I went with the stock 2.5. I don't regrete at all, I have put 10,000 miles on the car[8)]

Turbo charged engines do not need back pressure down stream of the turbo. The less down stream back pressure the great the pressure differntial across the turbo resulting in faster spool up.
