If you are looking for a bit louder but not overkill, I would say just weld a set of 2 chamber flows in the place of the stock mufflers. It wont really help any kind of horsepower gains, but you already stated that you arent concerned with that. The 2 or 3 chambers would be a good choice for you. The 3 chambers are a little bit more on the quiet side than the 2 chambers, but definately a noticeable difference over stock. I also hear that the FR500 and Steeda catbacks are of nice quality, and only marginally louder than stock (more so the FR500 than the Steeda). I would opt for the Steeda or the 3 chamber flows.
