Your favorite mufflers for your Magnum?

My thought at the time of buttoning up my Magnum swap was to keep it modest. The ~300hp motor just didn't warrant a loud exhaust and I liked the idea that at least with the hood closed, the car seemed totally stock. So I went with an inexpensive stock style muffler

Well...that has since become boring. I don't regret the subtle exhaust note but a little bit more noise and a less performance-restricting system is probably a better choice, especially since I spent the money on the headers. :D .

What are you running on your Magnum now? Are you happy with the sound? Did they free up any horses?
