Time for a new muffler, Advice? Options

[6G96GT]

I already have the ebay header installed along with a flex pipe and performance catalytic converter. I need a new muffler now and the piping that rides up and over the rear pass-side axle. I did have an Aeroturbine Muffler but I want something that will be more acomadating for my exhaust setup. Something that sounds deep and doesn't get tinny in the upper RPM range. Any ideas?

Ah, someone else got here to explain that all these ads for resonators aren't for resonators.

The Aero linked does not describe a resonator, but a straight-through: "A built in Resonator before our patented Air Foil is packed with high temperature ceramic packing." Resonators aren't stuffed with packing/insulation; absorption mufflers are packed. Resonators are hollow; they ring when struck. A straight-through muffler is often mistaken for a resonator because it isn't baffled, and because a round muffler appears much like a resonator from the outside.

Straight-through mufflers can be good designs; they are a modern take on the classic and now deeply outmoded glass pack. However, they address volume rather than tone. A smooth exhaust note almost requires a resonator in the system (some engines are smooth by themselves).
