I heard a truck with two of the biggest single 3" in/out magnaflows stacked back to back with a single 3" tailpipe and it was only one notch louder than stock, just deep and rumbly as hell. I liked it and I'm sure it flowed quite nicely still. He had Dynatechs with Magnaflow spun cats as well. This was a n/a 370 with a mid sized cam.

 

Two of the biggest 3" Magnaflows. Ben, wouldn't that have been 3"?
No sound clips?
