Muffler delete sounds the same regardless of NPP or Non-NPP.
Muffler delete is much louder than open valve NPP. Muffler delete will also have some drone on the expressways while cruising. It’ll sound badass under throttle though.
This will give you an idea of what a muffler delete sounds like vs non-npp muffler. Electric cutouts are basically a muffler delete with an on/off switch.
