The heat damage to the factory heat shielding was immediately apparent. The multi-layered metal was warped, brittle, and crispy in the areas closest to the catalytic converter. Keep in mind that Project Viper is a pristine example with less than 9,000 miles on the clock, and the heat shielding looks like this!
A close-up of the warped heat shielding shows witness marks where it was touching the muffler. Radiant and convection is bad, but conductive heat transfer is really bad. You don’t want the exhaust touching metal heat shielding that is touching the side sill or chassis, but as the factory exhaust burns and warps the OEM heat shielding, the heat problem becomes worse. While our car is hot inside, it didn’t seem to be as bad as the complaints of other owners with 30-40K on the clock. It now makes when our car’s heat shielding is this bad with lets than 9K miles.
After a little time with a rubber mallet, Will from RareFab was able to straighten the factory heat shielding back out to its original shape and not touching the exhaust.
We now have more clearance for adding some additional heat shielding.
After a little time, and some aluminized seam-tape, the side sill was ready to be re-installed. I was really pleased with RareFab’s execution here. Unfortunately we didn’t have enough StickyShield to do the entire inner sill, but we may do that in the future in a long-term review to see how everything holds up.
