What is your favorite performance muffler?

I remember when Flowmaster mufflers were just becoming popular in the early 90s. They seemed like they transformed a street car into a NASCAR stocker with that bellowing sound. Back then I drove a Camaro and considered a switch to them.
Here I am many years later, a Mopar man with these Flowmasters. I have been running 2 1/2" exhaust with # 42541 mufflers since 2002. I have been happy with the sound for the most part but the cackle is starting to wear on me a bit. I'm thinking of a change. I've read good things about the Dynomax Welded Ultra Flo mufflers. I'm thinking about replacing my exhaust from the headers to the mufflers to 3" with an X pipe. The TTI site shows a kit but they say their X kit wn't fit a car with a Gear Vendors. It looks like I'll be piecing a kit together and having the pipes bent at a shop.
What mufflers are you running?
