2001 9-3 Intercooler design change

I have read elsewhere that the 9-3 Base intercooler was restrictive due to its inlet and outlet pipes both configured on the same side (requiring two 90 degree bends internally. My 2001 9-3 Base has a straight through intercooler (inlet and outlet on opposite sides). Was this a recent design change? Will upgrading to a Viggen intercooler be worthwhile or will the additional size just increase the lag with the stock turbo. Also, I noticed that the pipe running from the IC to the intake manifold is a flattened oval for almost a foot, then opens up just before intake. Is this to increase torque response at low RPM at the sacrifice of high end HP? Should I replace this pipe with a round pipe?
Thanks in advance for any comments.
