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?

I'd also add the question of whether or not any aftermarket converters are going to have the durability of the stock converters?
I'm sure someone has tried some cat delete pipes...I wonder what difference those would make? If none, then aftermarket "high flow" cats won't help either. |
