Most of the retailer on the web offer a mid muffler(the big one) and a two piece section with a rear muffler. British Pacific has a good deal on a set up. I am sure that Atlantic British or Rovers North has some too. It is not a difficult install. The catch there is whether or not you have a completely stock system now or if it has been hacked.

British Pacific, check page 5
Atlantic British
Rovers North with "NRP"
I have a flow master mid muffler with the BP exhaust and rear muffler. I had a local shop install it with all of the stock flanges and hangers so I could remove and replace just as a stock muffler. I really like the way it sounds and most people do too. It is still quiet but with a nice deep rumble. With the rear muffler gone there would be a marginal increase in flow for a much louder exhaust. Just my $.02.
