I switched to Smarty mainly because I noticed some strange engine noise. Timing rattle or something else I dont know. The noise seemed to go away with Smarty. Then H&S put out a new update right after I started testing Smarty, and it made my truck drive really bad. Overall I was happy with H&S for the past year, with a couple minor issues. With Smarty the exhaust brake works better the exhaust has a deeper sound and I've got much better MPG. I think I'll stick with Smarty but still testing.

That 6.7 sounds good. Dose it still have the stock down pipe?

@RT440Robert Yes it has the stock downpipe then 5" straight pipe dumping out the side in front of the rear tires.
