The H&S has shift on the fly power settings which is a nice feature. H&S also shuts off the EGR system and does not cycle it like the Spartan.
As for using the stock exhaust with a delete pipe versus a 4" downpipe back exhaust, depends on the look and sound you want.
The truck is going to be a daily runner, used for family trips down state, tow a boat in summer, tow sleds in winter, and haul some home update materials/landscaping materials in the bed or on trailer. I am happy with the power it has now but am looking to try and get a few more mpg and the biggest thing is to get the longevity out of the motor.
Could you explain the H&S with the EGR shut off a little more please. Searching for info on it also.
How much better tone/how much louder is the 4" duals? My brother did a set on his duramax and it wasn't much louder.
First PSD owned but use them daily at work(stock of course). Thank you
