I have the Epco stainless pipes on my America. There is also a hotrod 1200 Sportster in my stable that the OL owns. The Sportster has gutless pipes and it is very loud. Where I can ride the piglet down the street and set off 5 or 6 car alarms, the Triumph only sets off 1 or 2. So, the Epcos are loud, but not shatter windows and get 3 tickets every block loud. They do have a nice classic Triumph sound to them.
