High flow cats
going with LG headers and borla touring exhaust. Should I put high flow cats or staight pipes. I live in a state without emissions inspection. What kind of performance increase will i see without the cats? Sound?

Performance increase will be negligible, but your emissions will greatly increase. There's no good reason to run without cats.

Good Reason to have cats!
In my last Vette I had the cats off for some track time. The smell gets really annoying. You come inside and the smell is in your clothes like cigarettes from a night club... Windows up and recycled air helps keep it away....but for a negligible performance gain it's not worth it to me...
