Hi joewj, I'm new to the forum and also just purchased 2013 limited, great ride, but also want a better sound, the ones Harley's are known for. I spoke with my guy at the HD shop, great guy,answered lots of questions, and yes good advise, pros cons of stage I vs II set up on a touring bike, and what there differences are. Besides being 2k plus, labor included, seems to me that there might be an advantage to listening to what you would want at your local shop. They seem willing to show there products. I'd be concerned about warranty issues and DIY this early on and on a new bike. Just my 0.02. I plan on the stage II but want to learn more. Good luck to you.
Looks like we're both looking for the same thing. Lets compare findings later on.
