I have a glasspack on my Zetec. You can hear a couple of my sound clips here:
#1 #2 I have a Flowmaster muffler, and the glasspack cut the droning down to almost nothing. It still growls nicely under acceleration. I like the sound of the Flowmaster, but I don't know about the sound of any others. If you have any questions just ask.
