Exhaust pipes, flanges, clamps, studs, nuts, and brackets sit directly in the path of salty road spray, where moisture and de-icing chemicals can stay on the metal long after the pavement looks dry.

That is why a simple muffler, catalytic converter, or pipe repair can become much more involved once the bolts have corroded into place or the flange has lost enough metal to stop sealing properly. Road Salt Speeds Up Corrosion Bare steel rusts when it is exposed to moisture and oxygen. Road salt speeds up that process by helping moisture conduct electrical activity across the metal surface. Every winter drive throws salty water underneath the vehicle. It works into threads, seams, clamps, and the small gaps between exhaust flanges. Even after the car is parked, residue remains on those parts ... read more
