A lot of people here have recommended getting the Flowmaster 40s to improve my exhaust.

The only Flowmaster that I can find is the American Thunder. Is there much of a difference between the 40 and the American Thunder?

Can anyone provide a link to a store that sells the 40s?

Regarding dual exhaust is it still worth it if I don't get headers? If I don't get headers would I be just as well off with a cat-back system?

your headers flow fine and until you really start modding you wont see much of a gain from exhaust anyways, unless you go O/R mid pipe and/or longtubes so just go with the flowmaster cat-back.. and i would think that the american thunder would be just like 40s.. i do know that supposedly 40s are flowmasters loudest mufflers

If the 40s are their loudest muffler then I definitely don't want them. I'm just trying to get a more aggressive sound. I would prefer the car to be quiet until I step on the gas.

american thunder is for old 350's and bigger engines get super 40's they were engineered with v6's in mind your local muffler shop will sell them.
