how to use exhaust wrap

Exhaust wrap is a fantastic way to improve performance, protect components, and reduce heat in your engine bay. But using it incorrectly can lead to problems. This guide will walk you through the process of properly installing exhaust wrap, ensuring you get the best results and avoid common mistakes.

Why Use Exhaust Wrap?

Before diving into the how-to, let's quickly cover the why. Exhaust wrap offers several key benefits:

  • Increased Performance: By retaining heat in the exhaust system, exhaust wrap helps maintain exhaust gas velocity. This can lead to improved low-end torque and potentially a slight horsepower increase.
  • Reduced Underhood Temperatures: Keeping heat contained within the exhaust system significantly lowers underhood temperatures, protecting other components from heat damage.
  • Extended Component Lifespan: Lower temperatures translate to longer lifespans for exhaust components like headers, downpipes, and mufflers. This saves you money in the long run.
  • Improved Sound (Potentially): While not always the case, some users report a slight change in exhaust note with the addition of exhaust wrap.

Tools and Materials You'll Need:

Before you start, gather these essential items:

  • Exhaust Wrap: Choose a high-quality wrap rated for the temperatures your exhaust system will reach.
  • Exhaust Wrap Ties or Clamps: These secure the wrap in place.
  • Gloves: Protect your hands from burns and abrasions.
  • Safety Glasses: Protect your eyes from debris.
  • Sharp Scissors or a Utility Knife: For cutting the wrap.
  • Wire Brush (Optional): To clean the exhaust system before wrapping.
  • High-Temperature Spray Paint (Optional): To coat the wrap after installation (helps with longevity).

Step-by-Step Guide to Installing Exhaust Wrap:

1. Preparation is Key:

  • Clean the Exhaust: A clean surface ensures better adhesion. Use a wire brush to remove any rust, dirt, or loose paint.
  • Measure and Cut: Accurately measure the length of exhaust pipe you need to wrap and add extra for overlapping. It's better to have a little extra than to run short.

2. Wrapping the Exhaust:

  • Start Wrapping: Begin at one end of the exhaust pipe, overlapping each wrap by about 50%. Maintain consistent tension to prevent gaps.
  • Secure with Ties/Clamps: Regularly secure the wrap using high-temperature ties or clamps. Space them evenly along the length of the wrapped section.
  • Avoid Overlapping at Joints: If you are wrapping multiple sections, don't overlap the wrap at the joints. This can restrict airflow and cause problems.
  • Finishing Touches: Once you've wrapped the entire section, trim any excess wrap with scissors or a utility knife.

3. Post-Installation:

  • Optional: High-Temperature Coating: For added protection and longevity, you can spray the wrap with high-temperature paint.

Important Considerations:

  • High-Temperature Resistance: Always choose an exhaust wrap with a temperature rating that exceeds the maximum operating temperature of your exhaust system.
  • Oxygen Sensor Placement: Be cautious around oxygen sensors. Ensure they are not covered or obstructed by the wrap.
  • Grounding: Ensure that you haven’t inadvertently grounded anything with the wrap's metallic fibers.
  • Safety First: Always allow the exhaust system to cool completely before handling or working on it.

Common Mistakes to Avoid:

  • Wrapping Too Tightly: This can restrict exhaust flow and cause damage.
  • Using the Wrong Type of Wrap: Using a wrap not designed for high temperatures will lead to failure.
  • Ignoring Safety Precautions: Always wear appropriate safety gear to prevent injury.

By following these steps and paying attention to the important considerations, you can successfully and safely install exhaust wrap on your vehicle, reaping the performance and protective benefits it offers. Remember, always consult your vehicle's manual and refer to the specific instructions provided with your chosen exhaust wrap product.
