Greddy Power Extreme for Turbo's

I just got a Greddy Power Extreme Exhaust for my 95 Civic EX. I was wonder looking at this Piping Diamator it is large. Looks like I would lose some lower end torque because of the loss of back pressure. What do you guys think? DO you think that it will be ok? Even the Greddy Site says that this is made for Turbo apps. I am running a SOHC D16z6.
