If you're talking about the entry pipe diameter (that connects the U-pipe leading from the muffler to the cats), yes- they should all be the same from the 2.5 to the 3.2 because the only difference btw the 2.5 muffler and the 3.2 mufflers were the exhaust tips (single oval vs. dual tips), and the upper muffler bracket mounting configuration.
