Alright, I like that APN Header. I really don't know much about exhaust. When I redo mine with that header and a super 44 offroad can I go straight from the header to the muffler then out the back? Deleting the Cat.... Do I need a cat? what does it do? and how would I mount the O2 sensor in my new pipe?
Sorry I'm so IGNANT
