Heatshield Products Muffler Armor uses our BioCool thermal barrier material to withstand 1,800 degrees Fahrenheit of continuous heat, which helps reduce radiant heat from mufflers by up to 70 percent. It installs easily and securely using Heatshield Products stainless steel locking Thermal-Ties, and it is water and chemical resistant for increased durability and longevity.
Heat from the car’s mufflers can be conducted through the floorboards and increase the interior temperatures to uncomfortable levels. For more rearward mounted mufflers, that same heat can raise trunk temps where there is little or no airflow to help release the heat. In addition to cooking whatever you’re carrying in your trunk, if you have a trunkmounted fuel cell, that heat can elevate fuel temps and hurt performance, along with increasing the risk of vapor lock.
Besides reducing temperatures in the passenger and trunk compartment of your car, Muffler Armor keeps the heat in the muffler, helping to maintain high exhaust gas temperatures. This increases exhaust flow velocity, helping to improve engine efficiency and performance. Muffler Armor can also be used on catalytic converters, by covering just the top half of the converter or muffler you allow the exhaust to breath but significantly reduce the heat transmitted up into the vehicle.
