Well i work at autozone and they had some cans of Engine Enamel Paint the 1500 degrees F in aluminum color for $2 a can so I took all the ones they had and I did my intake and to tell you the truth that stuff really keeps the pipe alot cooler not that its painted than before when it was just the natural polish. That stuff really works i even did some brackets on the engine bay and my front brake calipers just for authetic reasons.
