Is a 2.5in exhaust to small for supercharged 4.0?

    well... the stock exhaust on a 4.0 is 2.3in, and 2.5in isn't much larger, and a 2.5in exhaust pipe slips just over the stock pipe. running duals? or a single pipe? it run 2.5in back to a collector then out to a 3in exhaust pipe. but im sure there are others who know what your headers and cats are doing.
