Message Sorry no audio or video. I found a few additional clips on youtube by searching LaBree exhaust (they use the same sebring mufflers).

I wanted the same thing you were looking for, quiet, not-obnoxious, clean and close to stock. I actually went with only a back-half and not the full cat-back system (I kept the stock H-pipe section to try and keep the exhaust as quiet as possible). The sound is great, low at idle, no rasp, sounds solid once you really get into it up on the tach.

One word of caution though. Mine's got an in-cabin resonation, between 1800 and 2250 rpm. It's a low pitched drone, and it bothers me when I'm just cruzing along at about 25mph in 3rd, and that gets it right in that sweet spot. You'll find yourself keeping it wound up in 2nd longer to avoid it. It isn't something that even in hindsight would keep me from going that route, but it isn't perfect. I've heard that tack welding some venturies into the pipes just aft of the H-pipe will increase the backpressure at those lower RPMs, which will eliminate the drone. I haven't tried that yet, but probably will one day.
