on and consider it a heads up that your turbos are due sometime in the forseeable future for the sport500 upgrade or even better. No reason to assume that you will start smoking. Ash even said the car he saw it happen in pensacola stopped smoking as soon as they put the cats back on. You wont be any worse off than before, just sucks that you will have dished out the cash for the pipes and not get to enjoy them should you be so unlucky as to get the smoke.
