Any opinions on what would be the best choice for geat sounding exhaust for this model?
Hammer's right. Rather than 200 answers, do a "search" and you might find 2000 answers on here already!
Personal preference. Go to a dealer on a Saturday morning. People love to talk about their pipes, and let you listen. That's what I did. When I heard something I liked, I said, "that's what I want, right there" and that's what I got for my EG Classic. There are suggestions on here for pipes that I personally didn't like when I heard them --- even though those guys loved them. Go to the dealer, or a bike night before you spend any money.
