I never understood LOUD pipes on a touring bike. Just me I guess. Anyhow, I run SuperTrapp exposed disk slip-ons because they perform very well, are tunable, and are fairly quiet. I have the 4 speaker HogTunes set up with the amp, & HogPod and my radio is perfectly clear at 80 plus on the interstate. My wife and I will do 900 plus miles in a day and on a loud bike it's just too much.....jmo
