Looking into an o/r h-pipe, planning to keep the stocker for emissions testing. Do the 5.0s need MIL eliminators like the 4.6s or can I just plug in the O2 sensors and go? What's the best way to store the factory midpipe if I remove it so that the cats will work for emissions testing? Tape up the openings and store it in a bag? In the garage or inside?
Thanks,
