smog system
Im currently on hold for some new flowmaster 40s and i am on this run to get rid of all the crap on my truck i dont need. I know its illegal but i was going to run a dual exhaust system from my 91 f250 460ci by taking out the cat. and running the pipes striaght into muflers. But anyways i guess it is called a smog system and it connects to the top of the cat. and runs up to a pulley in the engine. And i wanted to know if it would cause any harm to unplug the smog system and do without it?
