So.. I have searched and searched, I know that most peaple do the mild2 wild switch, pull the fuse (which I have done already) or have done the "cut the muffler case open a bit and weld a stright pipe in " on NPP mufflers. I know about drilling a hole thru the case/inner pipes on stock mufflers and patching the outer hole . could that work on the inner pipe of the NPP ? and give it even more growl?
