Default 1992 f-150 exhaust

what are the advantages or disadvantages of running a 2-1/2" exhaust vs a 2-1/4" on a stock 302. would run from y-pipe back eliminating cat.

Probably not a lot; the exhaust backpressure will be very much lower without the cat, but this shouldn't be a problem for the egr, as it is the sonic egr system.
