I just had my side sills repainted. I decided to replace the heat shields. The old ones were obviously the original pieces. They were really big and "wrapped" around the muffler and cat. They were basically burned up so I decided to replace them. The new ones are not nearly as large as the originals. Does anyone know how those are secured? Do you just sandwich the heat shield between the painted cover and the exhaust system or is there some trick to it? Thanks.
