I have a 89 LX 5.0 and i was thinking of a converter less (offroad) Mac H-pipe or pro-chamber. I was wondering first of all, which is louder, cuz i read on the reviews here that the h-pipe is actually louder? But the pro--chamber makes more power? And 2nd, the main point, do i need MIL eliminators? All i see is ones for 96-02? Will the check engine light still come on? should i unplug it? Thanks for your help
