  1. Hey everyone, is it possible to change out the stock MY '04 GT3 exhaust for the Motorsports one. Obviously I know you'd have to remap the ECU, but if it is possible is there anything to gain as far as HP/Torque? Is it true that the GT3 engine needs the correct amount of backpressure in order to deliver on the goods? The way I've always known it was the less restriction the better the output, so if you could straight pipe it out wouldn't that increase performance?
