As stated, he does not have the NPP.

Thanks for clearing that up. That being said still lots of people are removing the NPP Suit cases because they think they are really heavy. One guy on YT replaced his with the 2 dual aftermarket Mufflers and weighed them against the NPP and they were a few pounds heavier than the NPP. So the NPP looks heavy but its mostly just a hollow case with a series of passageways and mysterious chambers inside.

i want to say the factory npp muffler weighed 38 lb and the aftermarket magnaflow weighed 36. i recall it being a negligible weight loss.
