Heatshield Products introduced their fiberglass exhaust wrap in 1985, and it has remained the benchmark for underhood thermal management ever since. Wrapping headers, manifolds, and exhaust pipes keeps heat locked inside the exhaust stream rather than radiating into the engine bay, protecting nearby wiring, sensors, and hoses while simultaneously improving exhaust scavenging for faster flow.
Tested temperature ratings you can trust. The wrap handles 1,200 degrees F continuous and 2,000 degrees F intermittent heat. Heatshield Products publishes honest operational limits rather than inflated peak figures, so the rating you see reflects real-world sustained use on a running exhaust system.
Reduces radiant underhood heat by up to 50 percent. Keeping exhaust gases hotter inside the pipe accelerates scavenging, which pulls spent gases out of the combustion chamber more efficiently. Cooler intake air and a cooler engine bay are byproducts of the same principle, supporting consistent power output across back-to-back pulls or extended highway drives.
USA-sourced fiberglass construction. The wrap is made from quality domestic fiberglass with a vermiculite coating that adds surface durability and raises the continuous heat ceiling. The white finish reflects radiant heat away from adjacent components rather than absorbing it. Every roll is manufactured in the USA.
Available in multiple widths and lengths. Rolls come in 1-inch, 2-inch, 4-inch, and 6-inch widths with length options ranging from 15 feet to 100 feet, covering everything from a single down-pipe to a full header wrap on a V8 engine. Select bundles include stainless locking ties so the installation is complete out of the box.
Product Benefits
- Original 1985 Formula: The founding exhaust wrap from Heatshield Products, proven over decades of street and track use.
- 1,200 F Continuous Rating: Sustains real operating temperatures on production and performance exhaust systems.
- 2,000 F Intermittent Rating: Handles brief thermal spikes from high-output applications.
- Up to 50% Radiant Heat Reduction: Measurably lowers underhood temperatures to protect wiring, hoses, and sensors.
- Increases Exhaust Scavenging: Retaining heat in the exhaust stream accelerates gas velocity and improves cylinder evacuation.
- Vermiculite Coating: Adds surface resilience and extends the effective temperature range beyond bare fiberglass.
- Multiple Size Options: Width and length combinations suit single pipes, full header sets, and everything in between.
- Made in the USA: Fiberglass sourced and manufactured domestically.
