X pipe and H pipe sound comparison

Does anyone know of a comparison between the two? Ideally on the same exhaust set up.

I like my exhaust, but wondered what removing the h pipe would do if I added an x pipe in its place.

IIRC, the x-pipe helps reduce rasp. Not sure if it has a big difference on exhaust note.

Generally H pipes create more of a muscular-burbler sound: think mustang, Camaro, Charge,
X pipes create more of an exotic sound think Aston Martin, front engine Ferrari, Audi R8
