What are these mufflers?

[Bouttime09]

When I purchased the car I was told that it was stock with the exception of the 3.55 gears. Recently found out that they were in fact 4.56, so I got to looking around. My mufflers didn't sound so stock, so I checked them out. They have "vortex" stamped on them...any idea what these are?
