What tune are you running in the car, chaddict? If you have a CAI and exhaust mods, you might be running lean (which can cause ping/detonation, though just those mods usually are not particularly dangerous). Adding headers and deleting cats can aggravate any pre-existing lean condition, and then if you get some obstruction in the fuel delivery (dirty injectors, dirty fuel filter, weak fuel pump, bad fuel, water, etc) it can catch up to you.
Get the car on a dyno and you will know where you stand.
