The Evo line is a full Titanium system (Titanium/Carbon muffler and headers), the Racing line has stainless steel headers and Titanuim/Carbon Fiber muffler.
The Evo system is a couple of pounds lighter, but performance gains are the same. Someone made a post here however, that the Evo system may require custom fitting on some bikes, but I didn't have that problem with my F4i.
