I got a 20 inch or so magnaflow on my 4.0, and it changed the sound a lot. From what I understand, the longer in length the muffler chamber, the deeper the sound. Also, it's a flow-through.

i'm running a dual outlet header, to a Y, to a flowmaster 40 series. it sounds nice and throaty while accelerating, but quiets down nicely at speed (which is my personal preference). if you want louder all the time, i hear the single chamber flowmasters are nice and throaty as well as glass packs.

change the size tubing, smaller tubing usually gives a higher pitch sound. the last foot or so affects the sound too, if you go from sat 2.5 inch to 3 inch using an adapter, you will have a louder exhaust, the opposite is true if you go from 2.5 inch to 2 inch in the last foot of the exhaust tubing. Like a trumpet.
From what i have heard, having just the muffler as the end of the exhaust, no further exhaust tubing from the muffler seems to sound the deepest.
I dont know why this always comes up about exhaust. Glass packs will make an inline 6 sound like a Honda if you want deeper exhaust than get wider exhaust pipes and use NOTHING but a flowmaster in my opinion no other exhaust comes close to the sound and performance of a flowmaster.
