im not aware of any aftermarket cat for dmaxes, but removing it is about all you can do to make it louder

A Cat delete pipe from MBRP is fairly inexpensive and will make that Magnaflow sound real good. Just be aware it might throw EGR/MAF codes by doing that, but there are easy fixes for that too.

Just do a Turbo Back 4" Straight Pipe. No Muffler or Cat.
