So far my girlfriend says she hears me coming 3 blocks down from her house, I guess she likes it. Lol

Someone from a performance shop who says he's installed a fair number of catless DPs on the IS posted here and said it's simply in the nature of the IS muffler. It must be whatever it is that gives off that nice sound stock reacts when you go higher flow with catless or high-flow catted DPs. At least this is my theory after thinking about this way too much. I gotta say, though, that other than the occasional rasp right at 5000 RPM, the IS exhaust with DPs (catless or high-flow catted) sounds totally bad ass. The neighbor across the street told my wife that she can always tell when I'm coming down the block as well, heh heh.
