Does anyone have info or pics of hood stacks? I know they seem to be mostly illegal, and will drop the soot on your truck. I'm about to go to a much larger charger, and think around a 6'' tall stack out of the hood would be pretty neat. Are there any kits out there to make it an easy install? Are there any stacks that somehow keep the water out without having a flapper on top? This would be for the 06. .
