its proberly because when its cold it will be on choke so extra unburnt fuel will be poping as it burns in the system but when warm the fueling/choke will cut back so no extra fuel to burn and go pop.

yup,hot engine burns fuel more efficiently so less waste finding its way through the exhaust system to make the pops

Stick a resistor accross the intake temp sensor to make it think it's still cold. Use a switch near the dash too select when to enable it, and label the switch 'chav-mode'.
