Cold start revs the engine high immediately upon startup... this builds instant oil pressure... I am not talking about pinning redline. There is no significant extra loading on the engine at 1500 rpms... it's the same load if not lesss. light throttle input takes the car out of the cold start loop... Oil pressure buolds the instant the engine turns over.
The car stays loud for a long time even after cranking because its dumping fuel and the secondary air pump is running. If you have a catless downpipe the air pump isn't needed anymore anyway so you're not gaining anything by letting the car go through its cold start cycle. All the cold start cycle does is warm the cat up for emissions purposes.
