High flow cats?

I've been looking for info on high flow cats for the ZL1 but I don't see any posts on the subject. I'm considering upgrading to a ZL1 and am looking for mod options. Would just changing the catalytic converters to high flow improve power and fuel economy on the ZL1 as it does for the SS?
