Anyone recognize these mufflers/resonator?

Probably more than half the people on this site are running or have run full length headers. Asking what to run will only get you twenty pages of people arguing about Magnaflows/Flowmasters/Dynaflows/Borlas...
You need to specify what kind of sound you want- quiet and smooth, a bit of a rumble, crackling like a Top Fueler, etc.
Selection will also depend on the rest of your exhaust- tubing size first; then full length, dumping in front of the rear wheels, underbody turndowns, etc.
And then what kind of a budget you're dealing with.
Stating what you want to end up with right at the beginning will save everybody a lot of needless typing.
