typicaly a hoter exhaust with a turbo thus the cat gets its job done better

The opposite of this is generally the case. The fact that you have a big hunk of cast steal in the exhaust path up near the head that soaks up a huge amount of heat means that the gas after the turbo is cooler and it take longer for the cats to light off.
On the other hand any supercharged engine where there is valve overlap will end up with unburnt fuel air mix going through to the exhaust, whereas if it is turbo this does not happen because the pressure in the exhaust ports is higher than the pressure in the intake ports.
