Are you allowed a down pipe in STX? I thought you could only change cat-back exhaust in STX?

Yup as long as it has a cat of the same type and the cat is within 6" of original position iirc

Im refering to your car getting hot and KR coming in. There was another guy on another forum that did autocross and posted up all his results. He had HPtuners and was saying after changing the tune constantly he finally came up with a good platform, the funny thing was withing a few degrees of timing of stock tables. I cant remember what his boost was set at though. He was having trouble with high EGTs at the end of his runs.
