Black exhaust wrap is engineered to retain heat in your GenSet or other power plant exhaust system. This heat wrap, maintains hotter exhaust gases, decreases the density, and that allows the exhaust gas to exit the system faster! Increased exhaust scavenging is produced and helping to lower ambient air temperatures. Black exhaust wrap also reduces radiant heat damage and can help keep workers from getting burns. This exhaust wrap features a new proprietary black coating, which holds its color longer than similar graphite coated wraps for optimum wrapping coating calculation. It can withstand 1200°F continuous and 2000°F intermittent. Our black exhaust wrap can be fastened with Thermal-Tie, hose clamps, or wire.

Our black exhaust wrap is asbestos free and is made from a base high quality fiberglass yarn. Black exhaust wrap is noncombustible and it is also water and fungus resistant.

Required equipment: safety glasses, dust mask, gloves

Optional equipment: long sleeves (highly recommended), water spray bottle or bucket, needle nose pliers, diagonal pliers

  1. Keep in mind; wrapping headers and exhaust pipes requires patience. Going slow and taking your time will help to make the wrap as tight as possible and that will hold the wrap on the pipe better and retain the most heat in the system. (If you are installing wrap on a powersport application, we recommend a 50% overlap in place of the ¼” overlap during the installation process).
  2. Optional: Soak in bucket of water or spray exhaust wrap with water (Figure 1). Soaking and spraying exhaust wrap can make installation easier and also reduce the amount of fibers. It is not recommended to wet HP Color Wrap (ceramic coating needs to be heat cycle before it is fully cured, soaking will wash off coating).
  3. It is important to start on side closest to exhaust port (closest to engine), wrapping down the system towards the exhaust tip.
  4. Make an initial wrap around the pipe flush with flange, then and wrap around pipe 3 more times at an angle, then secure end with Thermal-Tie™ (Figure 4) or hose clamp.
  5. After securing end, continue to wrap around pipe, using ¼” (or 50% overlap) with each pass and keeping tension on the exhaust wrap.
  6. Every 4 to 5 passes (or coils) around pipe use your hands to go back tighten the wrap. If you soaked wrap, you'll see water dripping out. Getting the water out is not the purpose for this, tightening the wrap is.
  7. If your primary tubes become so close together you cannot wrap them individually, wrap both pipes as one while using the same ¼” (or 50%) overlap.
  8. When wrapping the collector start with a ¼” (or 50%) of wrap overlapped on the wrapped primary tubes (Figure 3).
  9. Use Thermal-Tie to secure end
  10. Clean up and go have fun!

PLEASE NOTE: Your exhaust wrap will smoke after installation, it will eventually stop. Smoke is a normal by product of the curing process; your wrap will not burst into flames.  HP Color Exhaust Wrap will discolor after installation and turn brown; this is a normal part of the color coating curing process. The brown color will disappear; intervals will vary with exhaust temperatures. Cooler burning exhaust systems can take up to 5 days of normal use before the color coat completely cures hotter exhaust systems may take only 30 minutes.

It is not advised to wash exhaust wrap after installation, pressure washers can damage wrap and also cause it to change color.

Header and Exhaust Wrap Calculator

DISCLAIMER:

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.

GUIDE FOR CALCULATOR USAGE:

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

RECOMMENDED WIDTHS:

  • 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

SELECT OVERLAP OF EXHAUST WRAP:

¼" Overlap is recommended for automotive applications, a 50% overlap is recommended for all motorcycle, UTV, kart, marine, heavy duty and industrial applications.

ENTER EXHAUST COMPONENT DIMENSIONS:

* Pipe diameter in inches
* Pipe length in feet
Number of bends less than 45°
Number of bends greater than 45°
