This high temp exhaust wrap can withstand 1200°F continuous and 2000°F intermittent. It may be fastened with Thermal-Tie, hose clamps, or wire. Our marine exhaust wrap is asbestos free and is made from a base high quality fiberglass yarn. Marine exhaust wrap is noncombustible and it is also water and fungus resistant.

Header and Exhaust Wrap Calculator


This calculator is a tool to estimate how much exhaust header wrap you will need for your headers, downpipe, or exhaust system. Calculations are a guide only! Actual usage will vary depending upon installation. Tighter installation of exhaust wrap on the pipe results in smaller header wrap needed.


All fractions should be in decimal form:
  • 1/8 should be 0.125
  • ¼ should be 0.250
  • ½ should be 0.500
  • ¾ should be 0.750
  • 7/8 should be 0.875


  • ¾"- 2" pipe OD use 1" wide wrap
  • 1¾"- 4" pipe OD use 2" wide wrap
  • 3"- 4" pipe OD use 2" or 3" wide wrap
  • 4"- 5" pipe OD use 2", 3" or 4" wide wrap
  • 5"+ pipe OD use 3", 4" or 6" wide wrap
