Please don't flame me, but IMO I think the Dynomax's sound terrible. It is proven on dyno's that the Dynomax's make more power, but I just can't live with that Big Block Monte Carlo sound (sorry, that is what it sounds like to me, and sounding like any Chevy shouldn't be a compliment).
I have 2 chamber flows, nothing compares to them in sound (yes, I have heard macs, they sound good though). I am considering a muffler change though. I might go with 3 chamber flows or mac flowpaths. I want which-ever one has less drone. I will not settle for Dynomax.
Are macs set up like flows or do they have fiberglass packing in them? Also a word of advice is to listen to cars in real life (not the computer sound clips), because computers don't do them justice. I didn't like macs from a sound clip, but liked them on a car.
Just my opinion.
