Try the Hushpower, its what i went with on my stacks. Very nice sound and it works well.

imo, i wouldn't get the hushpower. it's good if you don't like turbo sound, but a packed muffler or a muffler with a restriction in the center (like the hushpower) cuts out the turbo noise. i'm partial to the expandit muffler on their (my old) 5" exhaust. my reversed, fluted 4" AFE muffler is alright, but a little quiet for my taste.



grand rock has the stack insert "mufflers" but they don't do much of anything.

Yes Stacks are louder then just the DPF delete. Also The Hushpower doesnt cover up too much of the turbo whine, i can hear the Ex-Brake loud and clear as well as the spool up.
