I've been kicking around getting a Road King or Street Glide - Debating on waiting for the 110th Anv models and comparing used ones. I decided that I'd like to at least get the Chassis/Frame of the '09 and up, but I noticed that HD went back to single exhaust for the '10 Street Glide (not Road King) then back to the 2-1-2 set up in '11 and '12. Does anyone know why? I definitly like the dual exhaust set up better - it just seems more "balanced". I've only come across a few 2010 models for sale - did the MC only do a short production run for the 2010 model year?
