Why don't you try debaffling first? It costs next to nothing (depending on what tools you already have), and it will give you an idea if you want to pursue the aftermarket pipes thing. Go gradually though, a full debaffle may be a little loud. I've just done the first stage. Drilled out the little plugs in the baffles. I can still hear the tick, so you'll probably want to do at least stage 2.
If you decide on new pipes, it's not that hard to change them, as long as the new ones are a perfect fit. A torque wrench is the only thing out of the ordinary that you'll need.
My biggest fear is when I die, my wife will sell all my guitars for what I told her I paid for them.
