4" Thick on a 3" 40 series. 5" is a damn big muffler.

Either way the 40 series is twice the size of the 10 series. There isn't room under there to tuck up a full sized muffler like a 10 series unless you don't mind doing the BFH mod to your floor pan or you can let the muffler hang lower that a 10 series would.
Just as a side note, if you do go 40 series you might as well get one of the clones for much cheaper.
