I went turbo back. But the stock DP has to be cut out inorder for it to come out. If i had to do it over again, i would just do a downpipe back just to save the trouble of having to cut the Stock DP out. and i could return to stock a lot easier. now with the DP i have, i will have to buy the piece of the DP that has the Flange on it to connect to the stock exhaust if i ever want to "Return to Stock" some day to sell it
