Sorry I mean their catted downpipe throwing a cell while other brand doesn’t . Is it because of the type of catalytic converter material used or ?Any catless downpipe will throw a CEL eventually. I tested it twice today and it came on around 30 miles again. My state requires yearly smog so I wanted to make sure a yearly install swap wasnt needed.
