R3D N3CK stated that the "high flow converters and H pipes" do little to restrict air flow and nothing to power levels. So Sorry but you are completely incorrect. I base this statement on a trial that I did on my 06 GT. I drilled the pipe and installed some steel flex tubing which ran to an air pressure guage. In stock configuration I had 8.3 psi back pressure at WOT and after removing the High Flow Cats and stock H pipe and installing the off road X Pipe and Flowmaster mufflers the back pressure had dropped to 3.5 psi. I don't have a track or Dyno locally but that decrease in backpressure has got to help.
