One thing I noticed when I drove the Viper is the intense heat generated by the exaust. The cabin of the car turned into an oven.

Many Vipers have caught on fire because of the heat generated in the side sill area.
In order to reduce the heat and possibility of fire my solution is to install heat barrier to the sill areas and wrap the exhaust with heat insulation.
I removed all of the weld spatter from the side sill area to create a smooth surface so the heat barrier would bond. I then primed and painted the sill area. Next I installed Thermo Tec's Adhesive Back Aluminized Heat Barrier rated up to 2000°F.
