Not any cat, but I suppose if you don't have the right size cat for your HP application, it will be an issue. G-Sport has some larger high flow cats for high HP applications but I doubt everyone is using them appropriately. They make cats that support very high HP applications up to 4" pipe range range but most people probably don't want to pay the price for them because they are expensive so they use high flow cats that are too small for their HP application and accordingly burn them up.
I've seen Hellcat OEM cats support well over 1000hp in racing applications.
