Cat installation question.
I have to put a Cat on my car for inspection. Right now there is just a straight pipe in the cats place.
My question is what is the metal tube that comes off of the side of the cat that appears to have a metal cap crimped onto it? Does this tube need to attach to the copper like tube that runs down the side of my exhaust?
After I put the cat on will I need to retune my car?
