Is it better to go with a 3.00 inch catalytic converter inlet/outlet, or a 2.50 inch? Which fits better? I've seen ads for both sizes depending on brand. Stock pipe 2.75 correct? Which is easier on the welder, so he doesn't mess up?

Get the 3". As long as the welder is even remotely competent... He will be able to weld it up.No F-Body right now
