I don't plan on doing anything until I get the other cat put on. I'm waiting on a stainless steel 3" y-pipe to see how well that will line up before I waste time adding the cat to my current TSP y-pipe. I'll get the cats welded in once I make my final decision so that will eliminate a couple of small leaks.
