50 FT Thermal Wrapping Purple Heat Tape for Exhaust Manifold Headers

High-Temperature 50 FT Purple Exhaust Manifold Thermal Wrap

Reduces under-hood temperatures and increases exhaust gas velocity by trapping heat inside the exhaust headers and downpipes.

The OEM Heat Soak Problem

Bare exhaust manifolds and tubular headers radiate extreme heat directly into the engine bay. This constant thermal radiation causes severe heat soak in surrounding critical components, including intake tracts, wiring harnesses, electronic sensors, and fluid reservoirs. Elevated under-hood temperatures drastically reduce the density of the intake air charge, leading to a measurable loss in engine horsepower and torque. Furthermore, allowing exhaust gases to cool prematurely within the uninsulated piping decreases exhaust scavenging efficiency, leading to slower exhaust flow, increased backpressure, and sluggish turbo spool.

The Engineering Solution

Wrapping exhaust components with this heavy-duty fiberglass thermal tape actively isolates the heat within the exhaust system. Rated to withstand 2000°F of radiant heat, the 1/16-inch thick, tightly woven fiberglass matrix creates a robust thermal barrier. By keeping the exhaust gases hotter, their density decreases and velocity increases, significantly improving exhaust scavenging dynamics and lowering spool times for turbocharged applications. The 2-inch width and 50-foot length (provided in 2 rolls) ensure optimal overlap and coverage during installation on complex header bends and collectors. Curing Note: During the initial heat cycles, the wrap undergoes a curing period (1-5 days depending on EGTs). Expect natural smoke off-gassing and temporary discoloration. Once fully cured, the material will transition to a baseline grayish/brownish tone.

Common Questions

Will this wrap fit my vehicle's exhaust headers or turbo downpipe?
Yes. This thermal wrap is a universal fit designed for automotive exhaust manifolds, tubular headers, turbo downpipes, up-pipes, motorcycle exhaust pipes, and marine inboard exhaust systems.

What are the dimensions and how much wrap is included?
The package provides 50 feet of total length split across 2 rolls. The tape is 2 inches wide and 1/16-inch thick to allow proper overlap on bends and collectors.

How much heat can this fiberglass wrap handle?
The woven fiberglass material is rated to withstand up to 2000°F of radiant heat, keeping heat inside the exhaust piping and lowering under-hood temperatures.

Is it normal for the wrap to smoke or change color after installation?
Yes. During the first 1 to 5 days of heat cycles, the fiberglass goes through a normal curing process that causes temporary smoke off-gassing and transitions the color to a baseline grayish/brownish tone.

How does wrapping my headers help engine performance?
Insulating the exhaust pipes traps heat inside the tubing, which keeps exhaust gas velocity high for better scavenging and faster turbo spool while reducing heat soak into your intake tract.
