To compare, my shortys were 7 each. My hiflow cats/pipes were 6 lbs ea. 26 total. I forgot the weight of stock manifolds and cats but remember I saved about 20 lbs overall. About right from what PepeLePew said

119lb entire exhaust weight from stock LS3. 95lb entire exhaust weight for ARH long tubes, high flow cats, x-pipe and mufflers. Have all the numbers written down, but at work now. Not sure if Bo included weight of cats, since OP just stated manifolds.

I had no cats to weight. Thats why I made the second post wondering if someone has a set they would weigh.
