Well, the audio clips do the talking for sure. My system is 2 1/2" and I'm also running a high overlap cam, idle characteristics are very close to those recorded.
From Doug's in car it sounds like a passenger could ride along with that for hours without needing medication. I'm going to check out the Borlas to be sure even though I know they are more costly. The higher cost is not nearly as valuable as getting the right part in this case.
Marc, I thought I would be fine with the Flows too, but they've worn me down. Your Mustang is a beautiful piece and clearly purpose built. Since you remember the flows I would agree the drone is probably why you got rid of them in the end, but they might be just what you need to get the sound you want. I do agree with Doug though, I have new interior and sound deadener and it seems as though I'm running bare steel floors for noise.
My Galaxie is a whole other animal, we tend to pack it with friends and family so turning your head and shouting to communicate has just gotten old. Plus, I don't want to carry ear plugs in the glove box anymore
Thanks to all for the feedback
