No jetting required for either mods.

you might want to wrap that can with some header wrap. it loses heat fast and drops your rpms down out of your sweet spot. had that problem with mine.

Id think youd wanna wrap the PIPE before youd wrap the can. Correct me if Im wrong.

if you want to keep the can on it, wrap it in 2 layers of header wrap. helps keep the heat in the can better. did this to bros mbrp for his viper and the rpms didnt drop on back to back wot pulls on lake like it used to. I was told this when i got my can from another member on here.

stock pipe has heat shield with insulation on it already.
you could wrap the 4x4 pipe too.
