  1. Why Does My Exhaust Wrap Smoke?

    You’ve finished installing your freshly wrapped headers and exhaust, but a few minutes after firing up the engine, you notice wisps of smoke coming from the engine bay and exhaust. You open the hood and nothing is on fire, but your freshly installed exhaust heat wrap is smoking like it’s going to catch on fire. Not to worry—this is actually normal for newly installed exhaust wraps that haven’t yet been exposed to heat.


    Exhaust/header wraps are made with binders, which are specially formulated starches that give the wrap’s fibers some structure and lubrication during the weaving process. Once the manufacturing process is done, the job of the binders is complete, and when exposed to exhaust heat they tend to burn off, creating the aforementioned smoke after using exhaust wrap.


    Another question often asked is why cheap wraps become brittle after a period of time/heat cycles and can disintegrate. This is the result

  2. Wrap BS: The Truth About Exhaust and Header Wraps

    Think all exhaust wraps and header wraps are the same? The correct answer to that question is an emphatic NO! While they might look the same, the truth is, the design of the material can differ greatly, and taking the cheap route when choosing a wrap can often lead to nightmares, not to mention a waste of valuable money and time. Heatshield Products’ Steve Heye has seen it during his career in the thermal-barrier industry and shares some of his experience to help you choose the best exhaust or header wrap for your vehicle.


    “There is a lot of BS out there,” Steve explained. “Some companies mislead temperature parameters, so people blow a gasket when their advertised 2,000-degree F wrap gets brittle and falls apart. The reality is, Heatshield Products is the only company with a truly 2,000-degree F capable exha

  4. Heat Insulation 101 - The basics of exhaust insulation

    Heat insulators retain heat in what they are placed upon. The most efficient way to fix a hot firewall, interior, or fuel cell is to stop heat at the source with an insulator to protect car from heat. Most insulators are exhaust wraps, but there are other options. Typical insulators (wraps) available on the market are comprised of fiberglass, which is good for 1000F of continuous direct heat. Fiberglass exhaust wraps can have special coatings applied to them such as “Vermiculite,” graphite, etc., which allow the fiberglass to take 1200F of continuous direct contact. Heatshield Products has even developed a proprietary HPTC coating which allows the glass to sustain 1350F of continuous heat. In addition, the wrap will remain flexible, strong, and abrasion-resistant even at those temperatures to provide car heat protection.

    Be cautious of any fiberglass wrap advertising or labeled as 2000F as this number is the maximum temperature a fiberglass exhaust heat wrap can withstand for less than 30 seconds. Anything above 2000F for an extended period of time will cook fiberglass exhaust wrap, causing it to get brittle and fall apart. That is because it exceeded the 1200F degree continual operating temperature, and the chemical make-up has actually changed and crystallized.
