    on my 06 2500 i had the cat and the 4040xl on and i loved it. it was just a low rumble at idle but when u got on it the sound was great. not bad at all when towing either.

    on this truck 06 3500 i have just the hushpower and factory resonator (megacab) and it sounds good also. great when towing and not to loud.
