Bill, are you saying that your like me? On my stang, I would listen to the thump of the cam, and the exhaust note, most often. Aftermarket headers, Bassani X-pipe and flow masters, sounded sweet. It was wild, how the X-pipe would make the exhaust scream, like a nascar, from 4000 rpm to red line. Totaly different from an H-pipe.
On the speed volume. X-wifes '08 escape had it. If I remember correctly. It had 7 setting levels of senstivity.
