Napa has 3A Stainless Seal bands, I use them on my 4" with good results, been through one winter, No rusting yet
I have not noticed any leaks either, and i am under my truck pretty often doing this that and the other thing LOL... Dynomax has a good band as well, Dynatech is a damn good clamp but pricey... 5" is 5" when you get the bands, 6" will be way loose...
S468 with some fuel and a Tuna or two MY Build
