|  | How Do I Install Exhaust Wrap?
Our exhaust wrap kits come with the fiberglass wrap material, stainless steel ties, and silicone spray. The fiberglass matting is intended to be wrapped around the exhaust part, then held in place with the stainless ties. The silicone spray is used after everything is done in order to waterproof the fiberglass. Otherwise, water will soak into the wrap and eventually cause it to rot.
To wrap an exhaust part, get your length of fiberglass damp -- a squirt bottle works great -- and tie wrap one end of the wrap in place on the pipe. Wrap the fiberglass in a spiral down the length of the pipe, overlapping each layer about one inch. When you get to the end, cut the wrap off and secure it with another stainless tie. If the tie is not long enough, you can hook two of them together to make a longer one.
Danger! The stainless ties are sharp, especially once you clip off the loose end. Use extreme caution!
Also, the fiberglass has annoying little fiber fragments that make your skin itch, and probably aren't good to breath. We'd suggest wearing a face mask so you don't inhale the fibers.
Once your exhaust part is wrapped, allow it to dry completely, then apply the silicone spray. The spray should be applied when the temperature is at least 70 degrees F. Shake the can for a full minute before using it, and often during application. Spray several light coats from 8-10 inches away. Be sure to have adequate ventilation; the spray is not good to inhale.
Once the part is one the car and you start the engine, the wrap and spray will cook a little bit, and will smell pretty stinky for a while as the silicone coating cures. This is normal. (If you want, you can pre-cure the part before putting it on the car by baking it in an oven at 400 degrees or more. But this will make your oven stink.)
Wrapped exhaust parts shed MUCH less heat than un-wrapped components, so your car and underhood area will be cooler, and the exhaust will be hotter. As it should be!
