so i finally have my x-pipe setup and my pacestters in my posession. now i bought the long tubes with the emissions setup on them. that was me thinking ahead b/c i am not going to be running cats for the time being. my town doesn't have inspections yet, but the towns surrounding us do, so i got the emissions headers for when my town has inspections and i have to run cats, therefore i will be able to use the headers the way they were intended to be used. my question is, what can I use to plug up the holes on top of my headers during the time i dont run cats? should i just use the EGR and AIR plug ins that are there, then when i go to get my car retuned, have them cancel it out of my computer?
