I did but I bought new cats first and gutted them got the spark plug non foulers. No codes and it doesn’t smell all that bad car sounds better. It’s a 2009 journey R/T. I don’t regret doing it I burn less gas and it has added a bit more horse specially top end. And so you know my model journey and the original cats were almost square. And they have 2 sections of filter in the original cats they are extremely restrictive
