Not sure why you mention the panniers. Any exhaust for the Super Ten should work fine.
Also not really sure what you're looking for in an exhaust. You wear earplugs, so don't mind loud, but the engine noise bothers you?
Are you just looking for more 'attitude' from the exhaust? There are some good sound bites for various exhausts on the forum, try some search attempts and see what sounds good to you.
Arrow, Akropovic, Two Brothers, LeoVince, GPR, Yoshimura, etc. in various flavors of carbon, Ti, Stainless are all out there. There is no "best", just what you like the look and sound of for your stated needs.
