Shouldn't be.
LT's are 3'' into a 3'' Y and then into 3'' IN/OUT Muffler.
But 2.5 is cheaper and most exhaust shops (around here) don't work at all with 3'' just 2.5 and under.

depending on your year truck. new trucks i was told dual plus 3'' is not needed. i run 3.5'' with stock set up, y into single with a dual outlet muffler. it runs great and sounds great too.
