Yes I have owned Harley's in the past and always kept the stock pipe. I never understood the open pipe deal? I only tour, so 200 miles per day on the weekend is nothing. Last thing I need is a super loud blab, blap, blap all day long. Try listening to to that for 500-700 miles in a day. 
The Harleys I owned were not touring glides but rather FXs, Sportsters, and Softails that I customized and the shorter pipes were more for style. I've taken long rides on those bikes and at highway speeds the sound of the wind, pavement, and other vehicles and the dampening of your helmet tends to somewhat drown out loud pipes to a degree. I agree however that short pipes, and especially open pipes, are not for serious touring.
