Best system for your VS with 1835 is the A-1 Sidewinder from A-1 Performance Muffler located in Santa Ana, CA (SoCal). A majority of VS (and quite a few on SOC) have this system on their Speedsters. They can be made with a single exhaust exit (like mine) or the double exhaust exit you want.
The sidewinder has a nice throaty sound under acceleration but it tones down to a nice tone at cruising speed. Like you, I'm a cruiser (not racer), but this system does enhance your engine performance when you need to accellerate.
A-1 Performance does not have a website although you can Google them for reference. The contact number is (714) 836-7201. The owner/proprieter is Tiger. He's very cool and helpful.
For your visual and sound reference, here is a video I made years ago with this exhaust. Hope you find this info helpful.
