Hey Everyone, I heard this loud rattle in my exhaust. I narrowed it down to the catalytic converter or muffler. I have also noticed that I don't have nearly the power that my jeep normally has. Can this rattle and loss of power be related.(I have no idea about exhaust systems) I have just removed the transfer case/transmission crossmember plate so I could get to the muffler easily. I figure since I am there I will replace the entire exhaust system, any suggestions? thanks in advance for any and all suggestions.
