So Marc, your saying you have both the heat Exchanger on your car with the Chicane Intercooler???? I asked Joe about adding a Different Heat Exchanger on my car and he said don't bother!! The design might be bigger but you can't beat the dual fans set up the saleen one has stock!! That was his Professional Opinion!! Of course its always good to hear what people think when adding something on if it was worth it or not!!!
