I am wanting to get a dual system put on my 04 quad cab. I am having a hard time deciding which way to go. I had a 03 regular cab with a flowmaster an dual crome tips out the back. It would damn near run you out of the cab. A guy a local shop suggested a Mellotone muffler, it doesnt quite have the rumble of the flowmaster. he says the flowmaster is a bit loud for the dodge trucks an I am begining to agree. I have read a few post on here about the magnaflow, but i don't know of anyone in my area that carries it. Does anyone know anything about the Mellotone? What about a glass pack, what kinda sound will that give me? What I am looking for is a low smooth rumble while idleing, a deep mellow sound when u take off an something that won't run me out of the cab at 75mph. Oh an I have a automatic with the 4.7. Any all all suggestions will be greatly appreaciated.
