OEM muffler heat-shield/metal sheet
Hi,
Is there really an important function for the metal sheet (heat shield?) above the OEM muffler? Mine is starting to come loose (rust), and I'm wondering if I'll have problems if I remove it entirely. I sometime track the car, so higher exhaust temperature. Thanks |

The are some batteries that have an open vent (Everstart, ask me how I know) that will leak acid went used on the track. The #3 coil pack can get hot and fail. Heat wrapping that part of the exhaust can help. I always open my hood after a session and, knock on wood, haven't had a problem with coil packs. |

I believe he's talking about the metal plate that resides above the rear muffler section under the trunk, not the OEM header, overpipe, or front pipe heat shields.

I would at least want to keep the shield over the Cat. The one over the muffler, not so much. |
