Note that the part numbers (where listed) are different. Different designs and diameters of mufflers. Has nothing to do with the material, just the shape/size of the muffler. For instance, the 17263 UltraFlow is a 2 1/2" pipe with an oval case, the 17296 UltraFlow is 3" with a round case

Flowmasters drone bad inside the car,but they do sound good at idle and going by and down the road
I had the 40 series on my 79 prior to sidepipes. The sound was cool, but the droan inside the car was horrible.
I'd get a head ache if I drove more than half hour at a time.I had a 50 series in an old GMC pickup that sounded great though with no droan.
I'm not sure if the droan was due to our fiberglass cars or just the 40 series Flow Master.
My Hooker side pipes and STS baffles are more quiet than the Flowmasters and they have no droan.
