I got a "race cat"... all it looks like to me is a resonator... not even that... Instead of a stock cat that has all these little baffels and little plates that "convert" the exahust to... whatever... mine is strait through with a honeycomb lining on the inner wall of the inside of the cat... thats all, basically stright through... and it dont sound bad or loud at all, thanks to my stock muffler pack that has been welded on my axel-back portion of my exahust.
