What is this sound??? exhaust question

[Boxtaboy]

My Dansk exhaust does not exhibit that raspy sound as the revs come back down, but it is also not as loud as a lot of these aftermarket exhausts. I think that noise is a byproduct of having less baffled mufflers, and is a character of the sound the car gives off if you don't have a muffler that is tuned specifically to cancel out that noise.

As you noted, the noise was not present when you had the stock, unmodified muffler on. I think the stock muffler does a great job of canceling out annoying drone and rasp, but as most people find, is too quiet. The factory PSE sounds nice, but also doesn't exhibit that annoying noise as it unwinds, so it's just a matter of finding another set up that gives you exactly what you want.
