I love it. It's quiet at idle & cruising at 1500 rpm, gets steadily louder, and is very authoritative at WOT. I get tons of complements on the way it sounds and when I need to be quiet, as in local police in the car next to me, I can be & don't draw unwanted attention to myself.
Right now, I have stock manifolds, the crappy stock midpipe with its million-and-one cats, and Dynomax mufflers welded in. Not the best for power, but it sounds nice and mellow, but not quite stock, at idle, and can get pretty aggressive with a little throttle. The car I'm hopefully selling mine for has stock manifolds (might be swapped for long tube BBK's), a Bassani off-road X pipe and Flowmaster 40's.
