With a stock exhaust and a DP, you can't tell a difference in sound unless you are driving around without the radio on, in which case it is a very quiet gurgle, but you really have to be paying attention to notice it to much. Hope that helps you some.
Kinda in the same boat but was wondering what kind if power you noticed with just the DP mated to the stock exhaust. Also, what AP tune did you use with that setup?
