Default MAF outlet size

Anyone know what size coupler should be used on the outlet of the MAF?

I think its 3.5/3.25. Most LSX motors including the 4.8's use 4". We have tiny *** MAF's. People say they are good for 400hp but I can't understand how. The inlet tubing that connects too the O.D of the stock MAF is super small compared to what other V8's use.
