I believe the H&S will also pass. I had a buddy with a 2011 duramax fully deleted with H&S pass another one with a 08 duramax fully deleted with H&S pass. And a 2012 6.7 powerstroke pass with fully 5 inch exhaust with H&S tuning. all of them said they turned the power level all the way down. Ill be going in this week or next week to get inspection on my 6.4 I'm running H&S so I will let you know how it goes. This is all in MA btw.
