Hey Paris, _not_ stupid at all... I think I addressed this in a post last night but I'll re-iterate it again...NA cars need some backpressure and remember he's using the stock cats again. The way the stock system is (quite different this time around) the cats are built into the headers so the drop in back pressure isn't quite as large as on the 6... We'll see what happens at the low end and high end as well tho.... The cargraphic changes the way the headers/cats are done and with higher flow cats you get a drop right there and right by the 02 sensors, which is true so we wouldn't do straight pipes on top of that (we did a cross-over etc.. for that set up) so it's kind of balancing out in terms of being the same as before (we'll test it and find out) since you've got the stock cats/headers and then at the "bypass" point it's essentially doing almost the same thing as it does in "sport" mode on a stock car and bypassing that stock center muffler. The difference now is that the center piece is no longer a resonated chamber. Make any sense?
