stage one and stage two exhaust

by Alan
(Columbia, Missouri)

I recently bought a 2006 Victory Hammer. When I purchased it, I had them install the stage 1 exhaust, and plan on taking the bike back to have the stage 2 exhaust completed. What can I expect from having this done? What I'm looking for is to have the pipes sound "louder". Will having this done increase the "sound"? I'm wanting to have the bike as "loud" as possible.
