Exhaust Tone: SIDO vs. True Dual

I currently have 2 Maggie High Flows into a 3" midpipe, into 18" SIDO Maggie muffler, into 2.5" tails. What am I looking at in tone if I changed to 2.5" ture duals; x-piped, into 14" mags?

Thanks.

Heres a video of a couple Chevys, same mufflers, left one SI/DO, right one true dualed. Thats the note true dual makes.

The 14" bodies will be a bit louder, and the true dual will rumble much better.

Would 14" 5x8 or two 18" magnapacks be louder?

I went true-dual on my 5.4L with 2.5" piping throughout.. x-pipe, 2 14" round bodies, and 2 18" 3.5 tips, all magnaflow.. check my sig for clip

It sounds pretty good to me.. quiet enough to be tolerable on highway, but loud enough when I want it around town..

11" body would be the very loudest, 14" round would be 2nd, then 14" oval, 18" round.
