I was seraching around the archives and found a lot of good info on adapting the SVT exhaust, but I dont understand one issue raised. Another member asked about the benefits of an SVT exhaust on the Zetec, and one response said you might lose some power becuase of it. So my question is..
How is that possible? I though eliminating backpressure was always a good thing resulting in more power at the wheels. Am I wrong?
