I'm thinking the carbon fiber would just spit out the exhaust, I know what happens when the steal valves fail and it aint pretty.
"Steal" taking something without approval of the owner.
"Steel" a hard metal, which in your reference, was made into ball bearings.
Across the street from me, a large tree, home for many song birds, constantly is attacked by crows which attempt to STEAL the songbird eggs.
From a professional type slingshot, I fire 3/8" STEEL ball bearings at them.....and have pretty much stopped them from visiting that tree.
This also has the added benefit, of keeping our vehicles from being targets for the crows, as they fly overhead, in the clusters of 40 or 50 that they USED to fly around in.
