Exhaust Heat Shield Insulation

Exhaust heat shields can be used on a manifold, header, pipe, mufflers and catalytic converters. The Heatshield Products Armor Series™ exhaust heat shields can stop up to 60 percent of radiant heat from the exhaust system. This system is easy to use and provides a way to wrap headers and exhaust components without voiding warranties. Browse your manifold and exhaust heat shield options below.

An exhaust heat shield works much like an exhaust wrap. Both retain thermal energy inside your exhaust system. The construction and installation of an exhaust heat shield is far different compared to an exhaust heat wrap. All the Armor Series™ exhaust insulation by Heatshield Products features our exclusive BioCool™ technology. BioCool™ is a non-caustic, non-flammable insulator made from a bio-soluble silica. It does not cause itching and has limited smoke or smell the first time it is heat-cycled. Capable of withstanding 1,800-degrees Fahrenheit continuous and 2,200-degress Fahrenheit intermittent. Our Armor series exhaust insulation can reduce as much as 70 percent of heat radiating up from the exhaust system.

How an exhaust heat shield works: By insulating the exhaust you focus or redirect the thermal energy where it belongs- in the exhaust system. This causes the exhaust gases to be thinner, this enables the gases to flow more quickly out of the system. The increased speed pulls the exhaust gases and intake gas through the cycle faster. This can lower intake temperature, creating more power. Additionally, this will lower underhood temperatures up to 50 percent. The benefit is making cooler intake temperature, generating even more power. Insulating a down or up pipe and manifold can also build boost on a turbo charged application more quickly. It will reduce lag and turbo flutter when on and off the throttle.

Direct contact vs standoff exhaust heat shields: The standoff heat shield car material utilizes a gap between the pipe and heat shield. This allows heat to escape from the exhaust system and radiate up, out, and around the standoff heat shield. This can reduce hot spots in the floor pan, but will still lead to general floor pan heat. Additionally, many clamp on heat shields just conduct heat though the metal stand off to the “cold” heat shield. The metal conducts heat when placed directly on the hot exhaust pipe. Using a textile to de-couple the thermal energy is a distinct advantage to the Armor exhaust heat shields. With the Heatshield Armor, you control the direction you want the heat to go, instead of just hoping it goes the right place with a standoff heat shield.

Exhaust heat shield vs. exhaust and header wrap: Our Armor series of exhaust pipe heat shields feature an outer aluminum layer. An exhaust heat shield, such as our Heatshield Armor are usually easier to install vs. an exhaust wrap. The armor also has an outer shield to protect them after they have been installed. This guards against water and the elements. It also gives an advantage to off-road applications, where an exhaust wrap may be snagged and fray from brush or other hazards. They can and should be installed in a header and exhaust warranty friendly manner. By using the Armor instead of a wrap you can leave a gap on an exhaust pipe, cover one side of an exhaust header, this will allow the pipes to breathe. By only covering a portion of the exhaust component, it should remain in compliance with most exhaust manufacturer’s warranties.

Ditch the itch, evolve your thermal protection with the latest in heat shield exhaust & muffler heat shield technology.
